Yeah, absolutely no problems, But I don't just use my bank accounts for cashing outs crypto investments, that's just asking for headaches and troubles.
I use them like any regular bank account, I utilize my credit cards for online payments, I take loans to buy more assets, I deposit and withdraw large amount of cash regularly...etc. So crypto investments in these situations don't raise any alarms, because banks look at your portfolio as diversified portfolio and not just a "money laundering" scheme to cash out your crypto.
Here's is the︀ thing, banks want to make money too, and if you are just using their services︁ to cash out, why on earth would they take the risk and work with you?︂ you have all the benefits while they have none, so it doesn't make any sense︃ to work with you, does it? 🙂
