check the coin bitcore - btx on bitcore.cc...pretty interesting airdrop system..every week 4% and every month 1% increasing..so in december every monday will give 4%, january 5% and go on... % on the amount of holding btx in your registered wallet..pretty easy, i am in!
And price how quickly dropping? 5-10% per week? it's not so easy and super effective (unfortunatelly) but if you like this way then sure it's easy to get more and more coins.
