I've experienced it when ppl say bitcoin's failing. They don't understand how it works because they're disappointed when it doesn't make money like they've foresaw. If they'd invested with clear sight they'll see short selling doesn't always work it's about long time possibilities so you'll have to sell later to amass profits.
I think people are too quickly claiming things against Bitcoin. I have trader friends that lately bought Bitcoin and tried to make money over it. When I was discussing with them, they kept claiming Bitcoin is dying, Bitcoin is failing etc. I think short term traders don't understand nature of Bitcoin so when they buy and wait, they are like they MUST make money through it OR it's fail. Average trader isn't aware how long term project Bitcoin is.
