Coin Swap is not completed yet. Only 9065 of 10000 BMXT coins are swapped. It seems 935 coins are "lost". So who have lost coins in old chain are needed of dev's reply about it
Maybe those coins have been lost, or the wallet, its DAT has been lost,
The possibility of that happening
It's not an assumption it's a fact. I personally didn't receive some coins. I see they in my old wallet backup but do not see in the Web wallet. And therefore I'm waiting for dev's reply about this issue
