yes, you're right, it's never too late, even though the Bitcoin price is currently at $ 29k,
you can still hope that the Bitcoin price will rise to New ATH next year, because according to history,
after halving the price of Bitcoin can reach 2x from new ATH, and it's worth $ 150k up to $200k, well let's hope it happens.
It should be clearly understood that with each halving the return on investment in bitcoin becomes less and less. You can earn 2x in almost any well-organized business for a year or two (and it is more guaranteed than investing in bitcoin and waiting - it will grow by 2x in a year or not). The more bitcoin is worth - the less interesting it will be as an investment instrument. This is my opinion and I could be wrong.
