After I read your post it got me thinking. The truth is the complaints have not piled up against flyp.me or the parent company holy transaction, there have been a few here and there but nothing substantial against them at all but if the OP claimed losses he should have continued his attempts to get his funds back.
This issue was a long time ago, I cannot recall all the associated facts but if the OP has given up on the matter (he last posted in October 2019 even though he last visited here in August 2022) I agree, I think bumping the thread does very little either to highlight the alleged scam or warn people off using flyp.me/holy transaction.
In addition, I only heard basically one side of this story, that of OP's. I have no idea what really happened between him and these two exchanges. And since this was all back in 2018, I'm wondering if they're under the same management.
Bumping this thread likely isn't going to do much good--and I haven't searched, but are there tons of complaints against flyp.me and/or holytransaction? I don't recall seeing many over the years.
