Hello
Anybody have any reviews on this site? Saw some bad and good reviews in my google searches. It’s supposed to be backed by Schwab and fidelity.

They have this short  term trade positions where you say wether it’s going to go up or down. For 40secs it usually gives 20% profit and more as the time gets longer.
Are there many sites that do this?  Crypto does something crudely like it but for only small sums of $’s

Well it’s not listed here in the above site

Hello
Where can I post issues about problems with withdrawals if the the exchange deals with other crypto then just BTC?
Having issues with a exchange called h5.multi-banks.com
Thier crypto bank has flagged my account as suspicious for arbitrage and says I have to wait a month or two before doing a withdrawal.
I had done several withdrawals to see if I could trust the site. There was also some issues with sending digital crypto to a coinbase crypto that was unsupported

Does anyone know a trustworthy exchange to convert USDM to USDT.
Can not do on trust wallet. Coinbase does not accept USDM. And Multi-banks exchange only sends USDM
