If you would like to give FTX a try, you can sign up using my referral link where you will get 5% of your fees back. You can read up more on the referral benefits here. I have been looking for alternative exchanges especially so when there is low commission. I think FTX is one of the exchanges that provided a pretty competitive rate. Its okay to have various exchanges although make sure you remember the passwords. With what Binance.com is facing, restrictions in various countries, it is good to have a few exchanges to allow transfer of assets if required. What I do is that I purchase Etherum, Bitcoin and stablecoins and then transfer them to either Hodlnaut or my cold wallet although I also hold small amounts on exchanges. Seedly came out with an article on the different exchanges available and I think it is really helpful....
