Focusing too much on the price that can be achieved in the possibility only makes them fail to build their portfolio when market volatility can be exploited. If they only have a few units, they need to collect more, they can accumulate with additional budget or in other ways. Taking advantage of price volatility can allow them to own more bitcoin, but they must have a good understanding of the market and its cycles.
Actually, there is no problem with the investment method and determining the target price that we want to achieve for those of us who hold Bitcoin. Some of us do like periodic purchases, but maybe some people who already have large capital in their purchases in past purchases have determined the target price they want to achieve.
Like those who bought Bitcoin last year, when the price was in the range of $ 50k- $ 60k, it is not a problem when they want to make a profit at $ 120k. Maybe they have a plan to sell their capital and keep half of it to continue their investment.
Although for us it would be a shame to sell at that price because of the potential increase in the future, in just a few more years, Bitcoin will definitely reach a better price.
