Maybe devs not understand, if won`t be new big exchanges (with big volume) that the coin will be died. Now airdrop allows BTX hold on the marketplace , but after , what will be after airdrop ends ?
High volume on an exchange does not necessarily mean higher volume for BTX, it is all about the demand. Getting listed on a big exchange does not always raise the value either, sometimes you get a spike in value after a new exchange announcement then a correction soon after, that is not guaranteed though. It would certainly be a welcome development to get listed on another exchange, a new/better option for traders. It is the development of the project, partnerships and marketing that helps create real value and demand though.
