Just as it is never too late to alive, I don't think it is too late to invest in Bitcoin. True, the price may have gone up significantly compared to what it was in 2018, but the fact still remains that you still have the opportunity to invest today. Not everyone who bought Bitcoin cheap in 2018 are still hodling it. Many sold off when they saw a pump.
Don't believe anyone that tells you that it is too late to invest in Bitcoin, because you're not.
BTC is always there for all of us, especially those who love BTC. If there are still people who say BTC is not good, just ignore it because it's not our thoughts, it's their thoughts. If you want to safely store your cryptocurrency money until you are ready to sell it for a profit, BTC is the answer.
However, currently in the crypto world its use is limited in commercial trading, but speculators use it widely which is one of the reasons for high volatility and can have a negative impact on investments in crypto. but it's still normal in my opinion because this is still in the growth stage.
