The problem is how you can safely buy cryptos? Most major US banks will likely close your bank account once they detects transactions goes to cryptos. Maybe I'm wrong, but few years ago it happened to few friends I know... Any good suggestion? Can't believe the damages trump has already done so far.
As with all of these petty rules and restrictions, there are always ways to get around them:
1. You can buy crypto using a PayPal account and no one can stop you. Transfer money from your bank account to PayPal (banks are fine with this, of course) and then just buy crypto on a
centralized exchange (e.g. Gemini, Coinbase) using your PayPal debit card. Or alternatively, link your PayPal account to the crypto exchange, if that's possible, and then buy your crypto that way. DO NOT USE PAYPAL'S CRYPTO WALLET! DO NOT BUY CRYPTO *ON* PAYPAL! You should never keep substantial amounts of money sitting in a PayPal account, lest they freeze it.
2. Physical bitcoin/crypto ATMs exist, you can buy crypto at these places, but they always have exorbitantly high fees, so they should only be used as a last resort.
3. This is probably unnecessary and confusing to some, but also as a last resort, there are some p2p (peer-to-peer) websites like Paxful where you can buy various cryptocurrencies by sending money to a seller via paypal or gift cards, but this might be a bit more complicated, slightly risky, and unnecessary, but they're there. These sites are somewhat similar to ebay, in that you should only do transactions with sellers who have a good reputation on the site.
4. I've bought lots of crypto using my debit card from my US bank and have never had any problems... try getting a better bank unironically lol. Opening a bank account with a smaller regional bank should probably work.
I'm sure there are more ways to bypass the ire of banks and acquire cryptocurrencies, but these methods should work for most people with US bank accounts.
