Coinbase, Strike, or BYDFi? Need some suggestions on exchanges for btc.

Hi everyone,

I am trying to get into btc. I’ve been browsing in some crypto/btc subs for a while and narrowed my options down to Coinbase, Binance, and BYDFi.

Security is definitely my top priority. I don't want my funds getting frozen or accounts locked for no reason, so a cold wallet is necessary.

I want to do some active trading (not just buy and hold), so I'm also looking for reasonable fees that work for my strategy.

Has anyone used any of them before? Also, any other advice for trading?

Thanks in advance!
