Investment exists fore a reason - to reap the rewards eventually.
So getting 10-20% out and continuing with the same reliable strat is totally viable.
Because if you only accumulate - you won't have reliazed PNL in the end.
Income at 10-20% is the income of short-term traders and is not in the same class as the income of long-term investors in Bitcoin. We can make accumulation on investments, but if it is limited to trading and getting such profits, I think it always requires more strategies because market conditions are not always the same from one day to the next. While investors only need a strategy to buy Bitcoin more often in a time that they themselves determine without having to complicate it with more strategies that sometimes some of them are useless for them.
Now let's look back a few years to the investors who were brave enough to buy Bitcoin in large quantities and are still holding it to this day, I think they have made a profit of more than 100% and that is a profit that is quite commensurate with the capital they have used for it and has outperformed traders who are only looking for a little profit in the short term with uncertainty.
