Before anyone starts to trade, I recommend to read a lot and do not suggest of speculators opinions. Often it is only pump & dump action.
Altcoins are hard to do even with expirence. Pump/dump is hard to see before it happens and when it happens... you might be left with a coin that never will be what it was in past Some good coins have peaked ... and likely are history.
Let's be honest small investments get you not very far. So likely hood of people doing them are slim. More go for bigger amounts I think a good example is ETH.... a lot are in deep believing it will be huge. They could be genius... who knows till we see down line. I personally feel better for storage of my digital currency in almost all BTC. Slow and steady wins the race I think.
