That's a great post Luc. I wrote up an example, it's pretty clear how you will be in a better position trading than holding .

Person A buys 1 Bitcoin for $2000. He holds it for months, not checking the price, until one day he sees it's at $4500 and sells, making a net profit of $2500. He is still only worth 1 Bitcoin at that point in time.

Person B also buys 1 Bitcoin for $2000. He holds it and is checking the charts, until the price reaches $4000 and then sells. When the price panic drops down to $2500 he buys back in and now has 1.6 Bitcoin! When the price eventually reaches $4500 he can sell for a net profit of $5200 and is worth 1.6 BTC at that point in time.

Of course, that's just a simple made up example. Imagine selling and buying back in multiple times!
