Why not binance?

I see a lot of ppl use kraken coinbase and etc. Why u all dont use binance.us for 0.02 taker? I couldn't believe it when i saw a fee so low. I ve been using robinhood and the fee abt .9

Do ppl not trust binance.us or what is the issue with that? 0.02 looks too sweet i am thinking to fully move to binance.us
