No, he is not trolling. He is just warning of the associated risks bitcoin is bringing. With everybody shouting "Choo Choo" or "to the Moon", we need people shouting out the risks. The market does have two directions my friend...
This was his original post:
Be warned! Just watch the charts -> decline is way faster then the uptrend was. Normally the crash is way slower then this!
Some exchanges are going to have liquidity problems. Let's unroll the big pyramide scheme

Sorry for all the pigs that bought over 100$ !
Never buy in a rally -> you lose more then you gain, if you don't know anything about profittaking -> buy and hold won't save you this time.
Thanks to all the bulls @ pigs for the nice profit. Going back to hibernation. Bear out.
This isn't a concerned person urging investors to exercise caution. Rather, it's someone trying to cause panic.
Shouting "Double digits incoming!" to counteract the "Choo choo" posts makes about as much sense as screaming at an infant to make him stop crying.
And yes, the information posted here affects price. I believe this forum being hacked helped contribute to the price drop Sunday before last. No justification for pricing tends to make people assume the worst.
