Been a hot topic is this community like 2018-2019.
Yes, I have heard of instant exchanges before, I've used them in the past like Changelly and Shapeshift, however, there is still the possibility that they will confiscate your coins, or selectively scamming, just saying.
I think it's not entirely fair that Changelly has such a reputation. I've been following them since 2017 and I've witnessed investigations into their company and all scam accusations. At the time of writing this review, much has changed — at least they've stopped being partners with Changenow (according to their statements on social media and the website), reduced the commission to 0.25%, and became more responsible about resolving users issues.
Not a long ago I swapped BTC via Changelly and my transaction failed. It was the end of September, just when the BTC went down to $8k). I was really appreciated when I saw that the support asked me to confirm whether I really want to exchange my BTC for a less profitable rate. So that case saved kind of a lot of money for me.
My point is, Changelly is becoming better then it was years ago.
