I dont think investing in bitcoin today is late cause the decentralized platt form is still new and so are others under it new and it has got a future ahed.bitcoin has not even reached its goal rather just starting.so no time is late to invest
I think yes it is already late but it does not mean that we should not invest money in bitcoin now, still bitcoin is providing opportunities to people to invest their money there, and get the benefit from its price, i think that after few months we may not be in position to trade bitcoin in current time again.
You might have missed the past trend of Bitcoin where the market condition or price is on the favorable side of investors, but I don't think it's too late for anyone to come and join the market as there will be more to come as expected. As long as it stays and we sustain its strength then I think it's all a matter of appropriate timing and preparing oneself for the required knowledge and emotional stability to face the risks. Gaining wealth in Bitcoin is not about who comes first or next, it's about who works hard for the success and stays positive and invincible to whatever challenges may come along the way.
