I tested it once again. I sent 3 lesser amounts to Coinexchange of 100 Bigup. Then sent one for 200 Bigup two of them disappeared. The Balances go offline when they receive a trigger amount. Then the funds are redirected to another wallet of their choice and when balances come back on line your transaction has been altered and the coins are missing. These Coinexchange people are crooks. They must need new track suits and plastic sneakers.
