I am programmer for last 35 years. Have been trading on CM since end of November last year. Deposited about 0.08 BTC. Site was a bit slow generally. The tick time for buy/sell updates was.......
If you work as the programmer of 35 years, and still haven't understood as the crypto exchanges are arranged - you are stupid. All personal addresses are tied to the account only for a deposit. All your current balances aren't tied to your addresses. If someone draws a conclusion, then the necessary sum is written off from a purse from all available entrances (which your deposits are). On it it is also useless to check balances through blockchain expolorer.
Whom hasn't reached yet that to administrators of CM to steal our coins, they don't need to transfer them from purses of CM. They and so at them.
