1. – Introduction and Review


If you’ve been around in the crypto space lately, chances are you’d have heard of In the first of this series, we will explain what is, and why we think it is probably going to be the most important crypto platform to emerge in 2020.

If you would like to start using immediately and skip the introduction and review below, go to 2. Account Registration.

Stick around, and we will show you why you shouldn’t miss out on this.

What is

In a nutshell, is an ecosystem comprising of a crypto asset brokerage platform ( Exchange on the browser), a user-custodial wallet ( Wallet on the smartphone), and a central app ( App on the smartphone).

Each serves a specific purpose:

  1. App
    • Smartphone app that plays a central role which links to the user’s non-custodial wallet and exchange platform.
    • Staking of various crypto assets for returns paid to wallet weekly.
    • Manages conversion of funds and fund transfers between fiat, crypto and card wallets for use with’s CRO VISA card and Pay merchant solution.
  2. DeFi Wallet
    • A user-custodial wallet where you the user are in control of the private keys.
    • Ability to link to a hardware wallet or use own mnemonic passphrase.
  3. Exchange
    A crypto asset brokerage platform or exchange for the trading of cryptocurrencies.

A App review App

The App is a well-designed smartphone app with a beautiful user interface. It runs on both iOS and Android smartphones and is a breeze to set up which we will explain a little later.

The app makes it a pleasure to view the price movements of over 200 cryptocurrencies. It is like having a little on your phone with a tap.

The app allows the user to buy a variety of cryptocurrencies from Ark to Zilliqa via wire transfer, credit card or with crypto such as BTC or ETH.

At the time when we installed the app, we found buying cryptocurrencies on the app to be closer to true value (i.e. cheaper than buying from local fiat-to-crypto exchanges) due to negligible spreads and no fee. We are not yet sure how this will change over time, but this is still the case at time of writing.

The App allows the user to manage his or her funds between three different wallets – the fiat wallet, crypto wallet and card wallet. To break this down into simple terms:

  • Funds you send into the wallet in USD or EUR via bank wire transfer is deposited into the fiat wallet.
  • Any crypto that is transferred from another exchange or wallet, or purchased with funds from the fiat wallet, will be deposited into the crypto wallet.
  • Finally, any crypto that is converted to spendable funds can be transferred to the card wallet, which can then be spent to purchase goods and services in the real world using their debit card powered by VISA.

As such, makes crypto spending very convenient for the crypto user.

In the app menu, you will also find options for DeFi lending (which we will not go into in this article) as well as an option to lock cryptocurrencies to earn passive interest called Earn (which we will cover in Part 4. – Stake and Earn).

This is a summary of what the App does, and it does it well. And we are told that funds are stored in a secured cold vault.

We’ll now move on to the Wallet.

B DeFi Wallet review DeFi Wallet

Most people are confused at this point, and wonder why there is a need for another wallet app when the App above already incorporates a crypto wallet. There is a good explanation for that.

The crypto wallet in the App is a centralised custodial wallet managed by They hold and control the private keys to that wallet, which also mean transfers between the App and the Exchange platform (explained next below) take place internally and hence no transfer fee is charged.

The DeFi Wallet is a separate app and is a non-custodial wallet. What this means is the user (you) holds and controls the private key to that wallet. It is not held by Should anything happen to’s vault, your funds would remain safe in this wallet.

Having said that, since it is an external wallet, all transfers into and out of this wallet will take place on-chain. This means that any crypto sent out from this wallet will incur a transfer fee. Likewise, if you were to send crypto from the App to the Wallet, a transfer fee would apply as well, just like for any transfers between any crypto wallets elsewhere.

One of the mention-worthy features of the DeFi Wallet is that you can use a Ledger hardware wallet with it. This makes the wallet a little more secure, although with the private keys being accessible within the Wallet, we are not sure if that presents too much of a security risk.

The DeFi Wallet stores many types of cryptocurrencies. If you need a private wallet that stores altcoins that are not available on your existing wallet, then the Wallet offers a solution. At time of writing, the cryptocurrencies that can be stored are:

  • Coin (CRO)
  • Bitcoin (BTC)
  • Ethereum (ETH)
  • MCO (MCO)
  • Basic Attention Token (BAT)
  • Celer Network (CELR)
  • Dai (DAI)
  • ELF (ELF)
  • Enjin Coin (ENJ)
  • Fetch.AI (FET)
  • Golem (GNT)
  • Holo (HOT)
  • Kyber Network (KNC)
  • ChainLink (LINK)
  • Litecoin (LYC)
  • Decentraland (MANA)
  • Matic Network (MATIC)
  • Maker (MKR)
  • OmiseGO (OMG)
  • Paxos Standard (PAX)
  • TrueUSD (TUSD)
  • USD Coin (USDC)
  • Tether (USDT)
  • Waltonchain (WTC)
  • Stellar (XLM)
  • Ripple (XRP)
  • 0x (ZRX)

If you like a private wallet that stores these cryptocurrencies, then the Wallet may be for you. See Part 2. – Setup and Installation for download and installation details.



C Exchange

The third part of the ecosystem is its exchange platform. Like most other exchanges like Binance and Bittrex, this is where cryptocurrencies are traded on a live and active international market. review Exchange

At the moment, the number of cryptocurrencies available for trading is limited, but is growing in number as we speak.

Users are also able to stake their CRO on this exchange for a return of 20% p.a.

Why We Think is Legit

These are some of the things we have learned about so far.

They spent $12 million acquiring the domain name This is a strong indication that they are serious about their business. A fly-by-night company wouldn’t spill this sort of dough on a domain name. Remember when Apple bought for $4.5 million back in 2011?

They pay a bounty to hackers to hack their platform. And from what we have seen, these bounty payments are not small. This is another good indication that they take their platform security very seriously. While most companies are often only concerned with marketing and advertising budgets, know where their priorities lie.

They have so far delivered on all offers and promises. On and off, have been running what is known as Syndicate events where crypto assets are newly listed on their exchange. As part of their marketing endeavour, these crypto assets are often offered to members to purchase at 50% off the market price. We recently saw the offer to buy bitcoin at 50% off once during the halving in May, and another time during the end of June. There are terms and conditions to these sale, and have been ingenious to use such events to drive value into their native Coin or CRO. Whether it is a marketing ploy or clever use of their advertising budget, end of the day, members are rewarded with buying bitcoin (and other cryptocurrencies) at half their market price. It is a win-win for both parties.

They have a working VISA card programme. partnered with a third-party provider to offer their CRO VISA Card which makes it convenient for an account holder to convert their crypto holdings into spendable funds on the card. The card is available in many countries around the world, with positive reviews from users who have had first-hand experience with using the card. There are also many other offers, benefits, cashback and rebates with using the debit card, which is summarised below:

CRO Visa debit card
Rewards and benefits offered by the multi-tiered CRO Visa Card. Stake higher levels of CRO on the App for more benefits and cashback rewards.

Personally, we are particularly thrilled with the 100% rebates for NetFlix and Spotify with their Jade Green/Royal Indigo cards. Rebates are paid in CRO, which is as good as money as long as it remains a denomination in their card programme and that it doesn’t fluctuate too much (especially in the down direction).



Why We Think will be Big

As discussed above, have made it highly convenient for users to spend their crypto holdings by managing funds in the in-App wallets and the debit card programme.

For the first time, we think this has been quite a successful implementation of crypto spending in the real world. A few companies have tried in the past with little to no success.

Making crypto spendable and easy to use is an expectation of things to come in this space.

At present, have managed to achieve a worldwide userbase of 3 million account holders (Update: 5 million users as of November 2020). While this is not a huge number in terms of world population, it is no less significant when taking into consideration the number of crypto users around the world.

We believe, if this trajectory path is maintained, may just have what it takes to bring cryptocurrency use to the masses by end of 2021.

At the moment, they do have some issues with handling queries. We found that the online chat responses are often slow, and we are quite certain it is because they may not have anticipated this level of growth within a short span of time. This reminds us of the time when some established exchanges had to close new registrations back in 2017 when the bitcoin hype was bringing in more new registrations than the exchanges could handle.

In time, we are sure will adjust to cope with the demands and scale themselves accordingly.
