Is OSL the best crypto exchange for you?

There's no such thing as the best crypto exchange in absolute terms — only the best fit for a given person's situation. The right choice for a business that needs a clean, auditable compliance trail is rarely the right choice for an individual just holding a small amount long-term, and both are different again from someone trading derivatives professionally. We don't recommend OSL, or anyone else — we give you what's independently verifiable so you can make that call yourself.

Here's what we've actually verified about OSL, specifically:

None of this tells you whether OSL is right for you — that depends on what you're trying to do, which jurisdiction you're in, your own risk tolerance, and practical details this register doesn't track (fees, product range, day-to-day UX). What it does give you is what's actually checkable, so you're deciding from facts rather than the exchange's own marketing.
