Hola coin isn't a mining app. You earn rewards by buying and holding the coin, also called staking. Buy 25 coins and earn 0.25 new coins every day. Buy 100 and get 0.45 every day. Buy 1000 and get 0.75 every day. Buy 10000 and get a 1 coin every day.So for just 25 coins you earn about 90 coins a year, that's nearly a 300% increase. And the value of the coin is rising too!
