honestly with bitcoin, the historically easiest and smartest trade to do is just trade your dollars for BTC when ready and 'sit in' like you say
that takes some amount of knowledge to realize
it's not really luck, it's just resolve if they know why they're sitting
All depends when you get in on a speculative basis really. I bought my first speculative Bitcoins in mid-late November. They cost a bit more than $700. At this point in time, some 3 months down the line, I would actually be underwater as opposed to having taken thousands of the table......
.....and anyone approaching Bitcoin with that attitude right now, would be nuts in my opinion. Scary uncertain times directly ahead for Bitcoin.
