My local bank put my account under review because I exchanged 200 ETH into fiat from Coinbase and transferred the USD to my account. I hear PNG, Bank of America, and a few others are doing the same to account holders.
Can anyone recommend a US bank that is crypto-friendly?
If bank lets you to exchange crypro, it's already crypto-friendly. Remember that everything depends on value of money. I bet you will never have problem if you exchange 500$ weekly but so much ether in one time, it causes some doubts. (In my situation it's like: What is the source of money, why so much money, is it attemp of money laundering and etc silly ones). Send them what they want, every crypro-friendly bank you are looking for would do the same.
