An interesting strategy. I am of the opinion that you need to buy some coins and keep them until you reach a certain goal, then sell them. This is not necessary to do with bitcoin, you can also use altcoins.
It's how some of my friends do it, they buy some coins and park it and let it sit for awhile and watch the prices, hodling is pretty much the same as this one since it tends to get long-term instead of a short-term stint, if you aren't good or don't want the hassle that trading has then you should probably do this.
