Here's what you must consider before picking the best exchange.
- Go with the higher security
- Have a SAFU(Secure Asset Fund for Users)
- Hight volume and liquidity
- Variable and transparent fees or beware of Fees and Pairs
- Easy to access and good UI for new users
- Non-KYC for small traders at least below 2 BTC
Additionally, if you aren't ready yet, just try copy trading on the Etoro exchange platform. You can simply copy from the experts trading open accounts the same as yours, this might work for newbies with a small amount to start, but I don't know how much the minimum amount before you can start in copy trading.
