Bigone exchange is an exchange which deals with a number of virtual currencies which are up to abou 60. Verification just involves your phone number and password after which you will confirm your status as a human. But a problem which I faced was in the KYC verification. It also uses spot,margin and also allows fiat to crypto trading. Its trading fees are also very low with a value within 0.2% and also employs flat fee trading. Deposits can be made with OTC through AliPay and also through cryptocurrency. Security is very vital as theft of users funds cannot be neglected. This security can be improved with the use of anti-phishing codes and asset pins or passcodes. Another problem I faced was that i had to get to a very high level before i could get a minimal trading fee BigOne also has a loan system which gives users loans with a nice interest on it. The user binterface is nice with little or no bugs in it. The KYC verification and the time taken for deposited cryptocurrencies to display in user's account are the only problems i have with BigOne.
