I buy Bitcoin from Cashapp every day with no troubles. Every so often I do large Bitcoin buys and those are never a problem. I have yet to sell and transfer dollars to my Huntington account, however.

Closed my business account after 3 months, with no explanations. I think ACH to Coinbase must be the reason.

Semi-frequent ACH transfers to Gemini with no problems. Have not yet tried withdrawing USD to bank account, as I'm always withdrawing in ETH.
