With the mentality of most bitcoin investors, if bitcoin gets to $500k in 2030 for instance, most investors will probably not benefit from such bull and there are several reasons why this is the case. most holders wont benefit from it because;
1. Some will rush to sell immediately bitcoin gets to $100k and while this is not bad on the extreme, it tells us that staying invested when you are at profit is not easy.
When the value of Bitcoin was very small, holders never imagined that it would touch $126k. When predicting Bitcoin, if we say that it will touch $1 million, some will find it unbelievable. If you analyze Bitcoin, it is very natural that the value will increase by this amount in literal terms. There are some traders who have a short-term trading mentality, they sell when they get a small profit, but they basically lose more than they make a profit because they will buy Bitcoin again at a higher price later. Most traders are in a frustrating situation because they are more likely to make wrong decisions and lose.
2. some will quickly sell while waiting to buy back and when it dawns on them that rather than dropping that bitcoin is actually going up, they might get frustrated and never get to enjoy the bull when it eventually comes.
If there is instability among investors or traders, it is almost certain that they will never reach the desired goal. Because when the price decreases, they tend to sell in panic and when the price increases, they sell for a small profit, which is financially harmful to them. Make a plan to accumulate Bitcoin during each bull run or bear market and DCA until you have a decent Bitcoin holding.
3. Some that are buying in small quantity like $50 or $100 per month will still not benefit real good if they are not consistent with their buys. Bitcoin favors those with a more robust portfolio
You didn't specify what amount of Bitcoin you mean by a strong portfolio, but for an individual investor, the best decision is to accumulate Bitcoin in a DCA manner for 4-10 years regardless of the price. Or buy Bitcoin in line with your income and discretionary income.
4. Some that only speculate without buying will be the worse of them all because while they continue talking without putting in the work, it will only lead to an eventual regret because if you are not buying, no matter where bitcoin gets to, you don't stand a chance in benefitting from it.
Once you have a strong sense that having a Bitcoin portfolio is better than no Bitcoin, you should develop a strategy for accumulating Bitcoin and consider keeping emergency funds and cash flow available to keep you going in the long run as part of your best investment strategy.
