about a month ago I started actively trading a number of different alt coins (18) on Poloniex. I seeded my trading account with .101 BTC. Since I started I increased my balance by 300% and have pulled out my initial investment. It is definitely a great time to be an active trader in crypto-currency.
The strategy I used was taken straight from the legacy stock trading playbook, bollinger bands (https://en.wikipedia.org/wiki/Bollinger_Bands).
