The price began to decline strongly after the airdrop ended. Maybe it makes sense start again up an airdrop, plus a marketing campaign to promote a coin?
Normally means that if airdrop ends = no more selling presure on the market
There is also selling presure from masternodes/miners
There must come new features, partnerships, a real world use case for bitsend + a marketing campaign after that to attract buyers
But times will get better, all alts are crashing the past months
