If you think BTSX is going to fall, you can convert to bitUSD. Then convert back when you think BTSX is ready to rise. BUT, if you are not an experienced trader, you are more likely to be wrong and miss a rise in BTSX as a result, than you are to save money.
If you want to learn technical analysis, thats a good thing to do, but you should expect to be quite bad at it for years. If you dont have an entire market cycle worth of experience with technical analysis, you probably wont do very well at trading. Most people have to lose a lot of money to learn their lessons. Of course, this wont apply to everyone. Maybe youre just a prodigy. Or maybe you will never learn.
Finally, if you are inexperienced at trading, then buy and hold is the best strategy. Just try to buy when it has dropped significantly, and then hold tight. Your natural tendency will be to want to sell near the low, and when it is high you will be too greedy to sell. If you buy and hold through multiple cycles you will be well enough ahead no matter what your timing is that you should do well.
