So I found cryptoup UK https://cryptoup.net/ while looking for something lightweight to run a few quick tests. I saw a comment on an old blog from a UK-based trader and figured I’d give the link a try. The layout wasn’t flashy, and that worked in its favour—it let me just focus on what I wanted to do. I’m no expert, just someone who likes experimenting, and this fit that pretty well. It hasn’t asked for much commitment, which is why I’ve kept using it occasionally.
