Abit of an understatement. I started in November and am still no better off. When your up 400% take all your profits cause the Bitcoin whales take profits every 4-6 weeks, resulting in a mini crash of the alts.
Have yet to try it but i have a feeling i will make more money.
Of course keep the main players, Bitcoin, Ether, Dash, Ltc. Apart from that not much else keeps its value.
