It’s never late to join the bitcoin train because bitcoin price will even surpass the current ATH and even new investors can make profit from it.
You sound like a trader for saying that new investor can join the bitcoin train now and make profit when the price surpasses the current ATH. A new investor should not invest in bitcoin now because he wants to make short-term profits and sell when the bull run hits its peak. That is not how bitcoin should be used. Any new investor that is coming into bitcoin should come in because he wants to invest and hodli for long in other to have a large bitcoin portfolio in future and not due to FOMO.
The only thing that I can say about bitcoin price reaching 100k is that, it should be a big hope and encouragement for any new investor who starts his bitcoin journey now to know that bitcoin has the power to increase in value exponentially, so that he will take his bitcoin investment journey seriously with persistent and consistent DCA weekly accumulation over time in order for him to hit his bitcoin target and not to sell along his way up.
It is not late for a new investor to start his bitcoin journey despite the price of bitcoin because you are to invest with your discretionary income and hodli for a long time.
