If HODLing is a long term investment, its fast placed equivalent is bitcoin trading. Essentially, BTC trading implies taking advantage of the highly volatile nature of bitcoin. This technique requires practice and market knowledge, so be sure to do your homework before even thinking about giving it a shot.

To get you started, here are a few styles of trading:
Day Trading
Swing Trading
Arbitrage

It takes a lot of practice to make money out of bitcoin using these methods, so don't expect to get it right on the first try. Just do your own research, figure out which approach is best for you, and believe you're going to be on your own path.
