The whole altcoin scene is now taken over by crypto-mafia pump and dump / fud groups. This is why honest coins are struggling to take top positions - because there was no insider trading with these groups to mine virtually free coins. This will be good in the long run but it means all the trading volume is still stuck on scam coins.
Really I'm waiting for $500+ bitcoin again to attract honest money back into the altcoin scene. I hope it gets there. Nonetheless I'm sure we can do well with NAV if the innovation keeps on coming which offers superior technology to the majority of coins.
Basically there are very few 'smart investors' willing to risk big sums of money like the good old days of 2 years ago. Even me, who would drop thousands of dollars onto coins in the past will not dare.
I don't know how much longer these scams will go on for, they definitely are not making as much money as in the past. But I bet that where even $1 can be made some asshole will try.
Crypto currencies. A chance for humanity to give power back to the people. Still victim of our own greed and stupidity.
