heres my strategy.
1.buy doge at 56-57 sell at 58-59
2.buy litecoin at 2.65 sell at >2.7
3.buy darkcoin at <1.90 sell at >1.90
4.buy 42 coin at 5.1 sell at >5.1
5.buy ripple...just buy it and hold on to it until it rises
6.buy monero, its awesome
7.buy shitcoin below market price, pump it, dump it
invest >0.5 btc or dont bother

The risk is too high for the amount of profits in my opinion, but its a fun way to waste time i guess.
