arbitragecoins.com claims to do trading on deposited crypto and shows profit in USDT
but,
1. The deposited crypto never leaves the wallet
2. Withdrawals never go through
3. Customer service is claiming the site is hacked and withdrawals will take 2 weeks
It is a scam site beware!
It is impossible to trust such not checked services.
bibitbit.com perfectly is suitable for arbitration of cryptocurrency.
1) Free day on the test (proly projects of it won't allow to make)
2) It is possible to connect any exchange and a coin
3) The convenient interface through Telegram and flexible settings
