It has been more than a year ago, but I remember a thread from someone that bought himself into NameCoin at +$8 levels on advice of people from the BTC-E troll box, and he kept holding everything till the price started tanking to sub $2 levels. Troll boxes are full of garbage clowns that are willingly advising people to do something where they know it results in an almost guaranteed loss. Basically every exchange with a troll box offers a mute chat or hide chat function. Best is to go for one of these options.
Somehow I have been one victim of that troll box. They have been using a lot of accounts with different usernames as if they are different person. Keep telling one altcoin is going to pump and it did but just for 5 minutes I think.
I am a newbie that day and will just start to trade and thats it, they got me. Thank God I didnt spend much.
You wont know about the next pump specially with bitcoin. But with alts, it could happen as if someone is controlling it.
