Just read news in my mail inbox with heading "X-Cash Nov Airdrop 100000 XCA (Listed on cryptopia)" Only came to know from here that it gets listed in one of reputable exchange. I love Cryptopia, but don't know how around Billions of X-Cash now available for selling at Cryptopia.
Dont know how much coins on Crytopia, but X-Cash making a airdrop with 1B Coins each month. I think you got email from a spam email for Airdrop User. Try to join X-Cash community for more information.
