The problem many people face is determining when the prices are low enough to indicate a buy and high enough to decide that selling is the best choice.
Bitcoin investment is not about buying low and selling high. That is typical trading of Bitcoin, not investment. The moment you have this mindset from the onset you are likely to not succeed in your investment. The best
such mindset are set on Altcoins and not Bitcoin, Bitcoin volatility I such in a way that you just cannot wait to buy low and sell high or else you'll definitely miss on mouth watering opportunities.
And I agree with you the chances of succeeding by buying low and selling high in Bitcoin are slim, Rather using the DCA strategy encourages a better chance of succeeding!.
It would be very wrong if there are people who still have the mindset of buying Bitcoin to sell it again in the near future just because there is a slight increase in the price of Bitcoin. Although the person may have bought Bitcoin at a low price, but if the goal is not for long-term investment and only wants to take a small profit like a trader, of course such an action will not provide better benefits for him.
Because Bitcoin is always better stored for the long term with a much greater profit target and this has been proven many times through the four-year cycle that has occurred in Bitcoin, so what are you doubting? As for altcoins themselves, I do not recommend that they be stored in the long term and are indeed worth trading in the short term for any profit because the profit can also be used again to buy Bitcoin.
