Most of the time there are those people who have been saying that it is too late to buy bitcoin for many years now. Too late at 1k, too late at 10k and so on and so forth.
It will always be "too late" because the current price where we talk about bitcoin is the highest price at the moment. You do not know how high bitcoin can go and our reference is always the previous or current all time high amount. That is the ceiling for us. Bitcoin will always increase over time. No use of doubting yourself every time you want to buy bitcoin.
