Been with Lloyds pretty much my entire life but I'm now considering voting with my feet and leaving.
I've been looking at
Monzo bank. Anyone here using Monzo or got any other recommendations?
I emailed Monzo with a few questions about crypto trading, etc, and received a very favourable reply (in less than an hour!).
You should consider leaving. The banks don't give the slightest damn about your loyalty to their business. They only see you as a number in their revenue statistics. If they actually block your credit card from buying crypto, then stop doing business with them. Just move to another bank that will.
