You won't know until you try them yourself, if gou are someone who have no problem with KYC verification, you will find OKEX, Binance and MEXC the easiest ones to use, this is my very best crypto exchanges and I can't recommend to you because you might not like them, some people still like Pancakeswap style exchanges and this style is like dex platforms, where you just connect your metamask wallet or trust wallet and do the magic, viola! It's done, so which one are you? Only you can. Figure that out mate.

My warning advice is stay away from any crypto exchanges that are not popular, stay within the top 10 crypto exchange list, you can find the list on coinmarketcap using google search.
