I managed to sell 5 BTC just before the recent buble
What bubble?

you do know what a bubble means right?
What happened this week was a massive dump due to negative news. (Short story: China banned deposits to BTC exchanges)
That has nothing to do with a bubble...
Exactly! Finally somebody who gets what the word "bubble" means.
As technically savy as most people who are into BTC are (I'm not at all), as little do they know about trading. Most BTC-people seem like they haven't even traded candy in the school yard.
