You are very fortunate to have entered this crypto space so early. Many, unfortunately, discovered cryptocurrencies much later (, and some will yet discover them). Perhaps this is also a generational issue. As an example, I first learned about crypto during the 2017/2018 bull run. However, I passed up the idea of investing at the time because I deemed it too late. Well, we all know how that ended. 
That's the thing, I don't think that it's too late even if you started buying Bitcoin now. I mean, who would have said at the beginning of 2017 that BTC will make x20 by the end of the year? I don't remember any sort of predictions like that, and as I said, many told me that's probably too late to buy BTC now, and even I was kinda suspicious but then remembered how I thought the same first time i heard about it, back in late 2013.There is an old Chinese saying "The best time to plant a tree was 20 years ago. The second best time is now." I think the same philosophy applies to the current crypto market.
Exactly! What I advice all people that are just getting into crypto is DCA into BTC, buying as much as they can, when they can, instead getting upset that they can't buy one whole Bitcoin and then focusing on shitcoins.
