Those who thought it's too late to buy bitcoin when it was over 50k can see how much Bitcoin has gained in less then a year.
Sometimes it's blessing in disguise that we forget things we have in our custody like Bitcoins. But Bitcoin and just forget them (without losing the keys)
You're right. Buying Bitcoin can't be considered too late because in the future there will be another profitable story for those who buy Bitcoin at the current price.
If you currently have enough money to buy 1 Bitcoin, just buy it and store it in a secure wallet such as a hardware wallet. You only need to store the seed phrase well in a safe place, then don't worry too much about the price for a year or at the end of this year go to the market to see how much Bitcoin is trading.
