Experienced people will never buy Bitcoin when the price is rising, they tend to wait for the price to drop and then buy and store it for a certain time to take big profits later. Therefore, in investing in Bitcoin, never FUD and FOMO and must be able to manage emotions so as not to get caught in big losses.
Your first statement is wrong. I believe that an experienced person understands that the best time to buy Bitcoin is now whether the price is going up or coming down. It is influenced by the goals, risk tolerance, financial level, and strategy of the investor. For an investor to buy Bitcoin when the price is going up doesn't make him an inexperienced person. He might be buying using DCA and dont care about the price as long as he is holding it for a longer period. You see a lot of people buying now at 63k to 64k in the market. They are buying now because they do not want to buy at 100k or above.
At the end of the day, it is our choice to choose how and when to accumulate. If you choose to not buy Bitcoin when the price is rising then you're either waiting for a dip or a comfortable price at the bottom which may be uncertain. There are disadvantages in timing and waiting for a dip to buy Bitcoin if you are a beginner or one who is still in the accumulation stage. You may never get to witness the dip and have you wondered what if the price keeps going up, will you continue to wait?
In all the years of my being into Bitcoin investment, I have come to realize that I don't accumulate because the price goes up and it dont accumulate because the price is going down either. But because of my optimism for a long-term price. I dont care what it's worth now, as long as I can afford it I DCA consistently and stack up, what I do care about is in the next 10 years I will benefit from all the efforts I put in now. Soon companies will enter more into the market, news will spread and there will be more approved ETFs. If buying without considering the price of Bitcoin is the price am to pay for a better future then I will.
