cryptohp , they could see how much BTC, ETH or LTC I own in my Ethx wallet. Absolutely not safe.
I think you're right. We're working on revamping ethx.me and generating new wallet address for every transaction. The old wallets assigned to you will still remain active and any assets received on those will reach your ethx account.
