I'm trying to set up and account with Binance, but having trouble getting past the security check sliding thing on the phone app? They want you to add a cell number, but don't list the USA?

Is Binance available in the USA?

I got this online: U.S. customers can’t use the Binance platform, and the Binance.US exchange is very limited

I want to buy BTC with a debit card at the lowest rate?

Coinbase charges 3.99%.

What are my alternatives?
