I heard from a lot of people said " Coinsbank is a scam. ", " They will steal your money " it has not happened with Coinsbank but I have read many comments from the reviewer. Bittrex, Bitfinex even Coinbase there are many people gave a feedback negatively.
Has anyone ever trade with Coinsbank or Bittrex?
1. Is it good to invest in them?
2. How long will deposit by wire transfer be processed?
3. How long will withdrawal cryptocurrency be processed?

I want to buy cryptocurrency with Perfect money, Payeer or Neteller at the right rate.
I can't open Coinbase account so I'm looking for a new chance.
