Markets tend to behave cyclically and if you can hold on long enough while managing your exposure it can be a steady source of income and knowledge, although it can also be very painful at times. The resistance at $50k was so strong that yesterday the price retreated to $47k, luckily it didn't drop below $47k. today the market is back to support to the figure of $50k but conditions are still very weak.
The turnaround is incredible this time around and many assume that bitcoin will break through to $100k later this year and traders making such predictions are actually just trying to cash in on their long-held buy assets.
I would say that up and down are the only options in the crypto world, or in any market really and that is why I do not think that there is any other option to pick. Bitcoin sometimes goes down and in that period you buy it because that is what you should when its low, then it goes up and that is when you should sell.
Honestly it is all about timing but even if you time it wrong, if you buy when it goes down, it may keep going down but eventually will go up, so if you time it right then you can buy at bottom and sell at peak but even if you do not reach that level of perfection you will eventually end up with doing it correctly if you could simply just buy when it goes down and sell when it goes up because those are the only options.
