If your idea of trading the bitcoin in to trade in and out of bitcoin market, your bitcoin would be spent and you wouldn't know when you have gotten out wrongly and miss the opportunity and benefit you would have gotten if you hold!
I agree. If one all it does is in and out of markets then the benefits of long term holding will not be encountered. Plus, I feel that in this manner people don't value the coin as much.
It depends upon different market conditions that will enable you to go towards a proper direction but you have to be aware of everything that will help you choose the right direction. Currently, the market is in its bear stage as we know that downfall in price has occurred many times and now we are still in low market as it is stable here from a long time so I think it is the real time to enter into the market and should wait for bull market after investing here.
