The only good thing about Coinoah (coinhapx.com) is that they remind you why regulation matters. I found them after seeing their ad online. They are regulated in a jurisdiction with weak consumer protection. When things went wrong I had nowhere to turn. Stick to well-regulated brokers.
Pros: Multi-device support|Smooth onboarding|Wide product range|Full transparency
