It's never really too late to buy bitcoin if you're in it for the long haul. It's true that bitcoin has already experienced huge growth but with the increasing adoption of blockchain technology and crypto in general, there could still be opportunities for it to reach new heights. I see bitcoin less as s short term investment and more as a part of a diversified portfolio over time
Hopefully you are not too distracted with your ideas (and investment into shitcoins./crypto) or your beliefs about diversification are also not distracting you too much, especially if you are in your beginning stages of accumulating bitcoin and if you have some lame-ass ideas that diversification justifies getting involved with shitcoins prior to learning and investing into bitcoin first.
Also your use of the term, "blockchain technology" is another sign that you might not really know bitcoin very well and you are just spouting out some nonsense to try to appear smarter than you are.
