And why?
Most of the time I like to use kucoin. I am using Kucoin since the beginning of the Kucoin exchange and still, now everything is fine for me. Easy to use, Very user-friendly mobile app and strong security make Kucoin popular. I use Kucoin to trade most of the GEM. A lot of new altcoins get listed at Kucoin and as an altcoin trader, I like to use kucoin for this. They have overall good volume and liquidity. I also use kucoin to use the free robots, That is very easy to use and good for long-term investment.
I have also an account at FTX exchange, But I am not a heavy user of this exchange. I am holding a few FTX there and took the privilege of free BTC withdrawal. Whenever I need to withdraw BTC, I use FTX exchange because there is no charge for me to withdraw Bitcoin. I am holding a good amount of FTX coins for a long time. I strongly believe FTX coin will be like BNB coin and FTX is a good competitor of Binance also.
