Yes, back in the days, I used it (few times). It used to be good (on that time) but in the long run, it turned out to be a bad option for exchanging coins (due to amount of recent complaints, simple search on "
Scam Accusations" section would give you the whole picture).
and How you can trust it?
You can't. I suggest to look for an alternative instead (I no longer trust them).
I found it is one of the worst here in the forum but some of my friends using changelly for the long time but they did not get the any issue as of now bro. Recently he changed around 800 digibyte with the ripple he had.
May I know what is the exact issue they are doing for their consumers. If you share that instead of these kind of report link by the user it may clear to use bro. Thanks for the assistance.
