Big one exchange has a very high trading volume everyday and the liquid is very impressive. Seriously I was attracted to this exchange jot even because of the interface, but because of the liquidity and trading volume that was indeed impressive. The number of fiat currencies is very huge and has also added in one way or the other to the liquidity. The exchange prevent scammers to enter it users account through the use of Google authentication, and also have a two divided kyc process. Though I have done the basics and I am left with the advanced. The basics required me to just provide my face ID, ID name, my complete name and the state if my residence ( country). I had a nice trading experience with this exchange
