To me Bitcoin is the best performing asset in the world today and it is only visionary for anyone buying Bitcoin by obeying certain principles such as buying from your discretionary income, just buy as you can without any form of pressure to enable you hold for long.
It is dumb to buy low to sell high to buy again because the price is not stagnant while all your focus will only for you to see that Bitcoin goes lower so you can buy with the money you sold out and it may not happen, the idea of buying low and selling high to buy back is wrong.
Such an idea is indeed no longer suitable to be applied to Bitcoin because Bitcoin has become the best asset after experiencing several halvings so everyone must apply the long-term concept when they want to own Bitcoin and that has made everyone use the concept of buying it at all times with the income they have. I also agree with the concept you said where everyone should buy more without having to sell it at a high price because the concept of buying low and selling high is a trader concept that is indeed not suitable for use at all times, especially for investors who like to hold Bitcoin for the long term.
