I got in Feathercoin super early and got out at the right time.
Same for Vertcoin 500% profit.
Mintcoin got in kind of late but still made 80% profit.
NXT made 1000% profit.
Seriously go through my post history, I've almost never backed a losing coin. Mainly because I ignore most of them. I bought PPCoin when no-one believed in it and you could pick them for under a cent each (yes I made a lot of money). If I could be arsed I would bump up my topic telling people to buy it and I remember getting ridiculed.
I'm not perfect. I lost money on Bitbars. And only just broke even on worldcoin, but it took half a year and most of it was spent in the red.
Anyway, I'm backing Blackcoin. I could get out now at a profit but I truly believe in this coin. Most coins I ride the wave and then sell off, but a minority such as Litecoin, Peercoin, NXT etc I keep for the long game. I use maths behind my investments (have a degree in it) and if my assumptions are correct I see this being a big winner. The only thing we need to focus on is building a strong community now.
That means you was mostly early in, I'm now burned by NXT and Vert. Just was buying in tooo late... okey both are solid coins, but ATM they're not looking good.
