It's late for sure, but I guess we can say that it is never too late to invest in Bitcoin since we can always expect a higher market price, if you are going for a high profit or return Bitcoin is not the one for you since it would probably be difficult or even impossible to even like 10x on Bitcoin especially at its market price, but still because of the popularity of Bitcoin it is probably the safest investment that you could do in cryptocurrency since market price might not drop lower on the support, and good profit might as well but not something compared to altcoins.
I mean a lot of investors are always going for Bitcoin It is probably the standard for most traders to have a higher percentage of Bitcoin on their portfolio to minimize the risk and then just putting a small percentage on other tokens that have high rewards but a very high risk as well.
If you are going to monthly investment or DCA definitely invest in Bitcoin for sure, even at 100k$ I still think it is profitable, it's always going to be a guaranteed profit as long as your going to sell at the top.
Late for what? I guess there's no word like that really exist for long term holder. But for traders? Maybe they might get intimidated on the current goals it achieve and this make them start to doubt then decide not to buy.
This fear is killing the opportunity of other people to think good about the money they can afford to spend.
If they are really for long term for sure they not get bothered to pay attention on any of those unwanted schemes.
