What suits your preference might not be the most reliable approach to your investment. The thing about trying to study the market like you said earlier is that you have to time your buys and your sells. It is very risk to do that when you are a Bitcoin investor.

Timing the market is a strategy that even preference traders struggles with and it is exactly why it is dangerous for investors to practice it. When you focus on timing the market, you are putting a lot of pressure on yourself, and not one can really predict the future accurately. And as you try to sell for short term profits you will miss out on the bigger gains over the long run. If you are not sure of holding your Bitcoin for the long term then you shouldn't have started your investment in the first place.

I feel it is more better for an investor to look back at the massive growth of Bitcoin overtime for them to see more reasons why they need to hold for long term..remove the mindset o constantly trying to figure out the perfect moment to sell and then buy again, because you will be automatically acting more like a trader than an investor. The whole point of investing for long term especially in an asset like Bitcoin is to buy and hodl and not to be obsess over quick profits.
