I personally didn't have too much invested because of how late I was to the game, but still managed a 40% profit after cashing out just now, and now waiting for a buying opportunity as more 'doubters' probably exit Bitcoin in the days ahead, not coming back until its next stratospheric rise into the unknown at which point they'll say to themselves once more "I wish would have..".
So, if the doubters are exiting (cashing out), wouldn't that make you a doubter as well, at least by your definition?
Just saying... its the panic selling to reap profit "while you still can" that drives the trend further downward.
I could have reaped a huge profit personally, but instead I have faith in the system long term and didn't sell one coin. I will buy more if/when I can afford it. If you really have faith in the system, don't be one of the ones that sells out as soon as the ship rocks a bit. If you really want to help build things back up, make the decision to stay with it for the long term and then the rewards will indeed be much greater. It's all the speculators that fuel the crashes/corrections.
And has been stated here time and again - don't invest more than you can afford to lose. If people had that attitude to start, then things wouldn't get so volatile.
