You sold all? Really?

IMO at current BTC valutation selling "for good" (to cash in fiat profits) more than 35% of ones BTC stash is completely crazy, regardless of when you bought in.

If you bought in low double digits/single digits, then your profits are SO HUGE that selling only 20% will grant you a massive gain, while you still keep bullets for the "next round".

If you bought just a few weeks/months ago, then selling 20% is probably enough to recover your full investment, while you keep riding the BTC trading.

In any case, selling all seems like something you will bitterly regret in the near future. I guess you dig in the forums and read the stories of those who sold tens of k's of coins in 2011 (if not hundreds of thousands of coins), bought a nice house and a nice car and retired from the BTC scene for good. Just 2 years after those guys would be so wealthy that their kids and the kids of their kids would be all set for life.

Yep - it might not happen. But its the kind of opportunity you just cannot afford to lose
