Maybe some people may say that Bitcoin price is now expensive and thinking that they are late its because they are new to the scene.
Not necessarily to the scene, there are people who has been speculating on a rock bottom price from the time Bitcoin was even below $15k and Bitcoin disappointed then very much by soaring higher in price, but they failed to believe in the potential of Bitcoin and make a move to accumulating it. Those kind of people are Bitcoin spectators, no matter how the price dips, they would continue anticipating much lower dip and still not buy Bitcoin.
Well, they have themselves to blame for gambling with their chances of buying Bitcoin at a much lower price and following up with consistent purchases to accumulate good stashes of Bitcoin for themselves, rather than just folding their hands and doing nothing but speculate on Bitcoin price without being decisive and actionable enough to purchase a good quantity of Bitcoin for themselves and getting his profits from the compounding effect of it's price appreciation overtime.
