We should buy Bitcoin for the long term, and put a lot of effort into it, people succeed because of hard work! So we should be careful when we buy Bitcoin for the long term, sell it when the price goes up, then they can make a very good profit
Why did you say we should be careful when investing in bitcoin for long term? The people that are suppose to be so careful are short term investors and traders, if you are planning to invest for long term, their is nothing to worry about, just buy your coin and hold, to be at a safer side, make sure you make use of DCA strategy when investing. I know everyone will definitely sell when the price goes up, but not that you going to be monitoring the market, and when you are in maybe 10 percent profits you going to sell, if you can do that, then that means you are not holding planning to hold for long term.
Investing for the short term or long term is actually fine for any investor because the goal is still to seek profit, and each investor has their own goals and targets. If the price rises 10%, selling it won't be a problem they just don't want the much larger profits that can be achieved by holding it for the long term.
What I disagree with is his statement that caution is needed when investing for the long term, when in reality, he should be careful with short term investments, because selling Bitcoin in the short term wastes an opportunity. For example, if he buys Bitcoin at $80,000 and sells it at $100,000, even though he makes a profit, he won't have the opportunity to buy it again at $80,000, or even $90,000, or even $10,000. So, it's better to invest for the long term to avoid regrets.
