Seeing the current price of bitcoin, make me to feel regret for not investing in bitcoin when the price was $40k last two years, some of my friends that took the risk to invest small amount of funds in bitcoin when the price increased to $50k despite people were expecting bull season in that period, they bought bitcoin and hold until the price touched higher before they released for sale, and they were lucky to make a reasonable income when the price touched $100k, but they were deeply regret for not using huge amount of funds to invest in bitcoin, i no there are some people in this community that had such experience for not investing in bitcoin earlier. I don't think, I will miss the next bear season because I no there will be bear season after this bull season.
Regret is always the end product for those who failed to invest in Bitcoin earlier, just like the you, most people who knew about Bitcoin and had the funds to invest earlier when it was below $40k are regretting too, for some people it was due to ignorance, lack of funds, and their were some who were procrastinating with thought that Bitcoin wouldn't get to this point, well it's clear your doubt and instead of living in regrets it's time to take make ammends.
Why? Cause Bitcoin is still at it's early stage and it has the potential to even get to $1m in the future, so now it's at this stage it's time to gather as much as possible before it gets to that amount, I think those that are still procrastinating even while they missed the opportunity of buying it when it was $40 would regret more when Bitcoin gets to $1m in the future and they've got nothing in their portfolio so OP buy bitcoin and hold just like your friends did cause it's not too late and you don't have to wait for the bear season before buying it cause you would've missed many opportunities before it comes.
