But the main trick is, when my account was restricted it asked me to upgrade and the requirement for upgrade was Assets equity = 5000$ min and when I deposit more money it went upto 10,000$ and that's for sure when someone deposit 10,000$ it will go to 20,000$ and so on.
Yep, they would just keep increasing the requirement as long as you keep depositing money so at least you stopped before losing even more money.
What I would like to know though is how you found about Bityx? I am asking because its a completely unknown exchange that is not listed on either Coingecko or Coinmarketcap and their site was offline for quite some time lately (I was checking their website ever since they appeared here few weeks ago).
