This is the most simple and 100% working method. And yes it's boring and need a lot of time.
I don't consider that method boring. Because making an investment decision is not boring, it requires calculation, checking all the risk measures, and trying to figure out how they can be minimized. After doing that, you will definitely be doing some research on when it will be the right time to pull out your investment and take home some profit, which is also one of the most important parts as the reason for investing is to make profit, and when your first investment has actually yielded a profit, one also still needs to study the market, either the stock market or the digital market, in order to know when it will be the right time to enter back and expect a fruitful harvest in the next harvest season. So the process of planning all of this doesn't look boring to me, as one will have to study and make some decisions that will contribute to the level of success they could possibly achieve.
IMO, when you do something like this, even though it sounds good, it is more risky.
It's great if you make the right moves when you enter and exit but we can't eliminate the worst case scenario where you exit your investment and expect the price to go down but the opposite happens.
Doing research by looking at the indicators doesn't mean it will be completely correct as it just goes back to speculation but the results have 2 possibilities of being right or wrong.
I think it is better to leave the investment we have there as long as the target you want to aim for has not succeeded and make additions when the price has decreased and it is suitable to make purchases to reinvest.
