Now they require TX transactions that I transferred to their exchange. If you use this exchange, one day they may say, your account is frozen provide the TX transfer to our exchange that you made in 2020. I made hundreds of transfers to different exchanges from different exchanges, my account on bitcointalk.org exists since 2016. How can I remember where I made the transfer from, from which exchange or wallet. They demand the impossible.
I wouldn't say it's impossible
[it'd take a lot of time], but based on the content of your thread, I don't think they'll restore your access even if you provided the transactions on that period
[I hope I'm wrong]!
I don't want to give you any false hopes, but the following method might come in handy:
- Refer to the "known addresses of hitbtc" > Look for addresses that were used in that period (Block #610,690 to #663,911) > Cross-check their TX history with all of your addresses.
