The same scenario will happen if someone invest $1000 in one of those coins, that type of altcoins suddenly go up and make 20% - 40% at least at every dump.
The problem with that strategy is that, there are too many of them now.
It is like picking penny stocks. Or... picking lottery tickets. Same thing.
That's why I always prefer to be on the safest side with Bitcoin. It earns less but when things go bad, it also loses less.
Still, It is a great pleasure to watch the OP's winnings. If I wasn't a coward, I would follow him.
And another thing is, even the OP don't fuck with those shitcoins. He is still with relatively safer coins like LTC mostly. I can't even trust LTC.
