There are some website over the internet that gives you free coin in every few hours/ established times. Those websites only gives a small amount of money so be warned!
here are some websites that I frequent for their bitcoin.
This website gives you free bitcoins / doge coins every 1 hour and will give you a chance to win jackpot up to 200$ (150$ for doge coin) with a 1:10000 chance.
aside from that. this website also provides gambling, in which you can multiply the bit coins you get from the free rolls (or bitcoin that you buy if you want to gamble fast but I recommend not to.. at least I try haha)
if anyone has their own recipe surefire in the gambling I would gladly share it here for other viewer if you like.
oh and you would need a place to keep those bitcoins. check here for those
here are other place that provides free coins
