I think that it has become very difficult to get into crypto over the last couple or three years simply because of the rapid price increase. That's great for early adopters, certainly, but now prices are so high even on some of the best altcoins that those with less resources will have problems entering the crypto world. That's not to say it's not possible to buy some relatively cheap new altcoin that eventually skyrockets, but that's a lot easier said than done.
That is ridiculous to judge the price of bitcoin as compared with various alts based largely on unit price - rather than fundamentals and deeper context.
Sure there has been a considerable price appreciation in bitcoin and also in various alts, but that does not mean that bitcoin is more over appreciated compared with various alts... which seems to be your suggestion to invest in alts because they are possibly more affordable... NONSense!
I will concede that all of the cryptos are somewhat gambles as compared with some traditional investments, but bitcoin likely remains the strongest of the cryptos in terms of fundamentals and in terms of its various network effects - and that is considering longer term prospects for bitcoin, as well.
So, yeah, be careful if you are overvaluing various alts based on unit price and some kind of perception that they may or may not be going places or they may get pumped (or dumped), and sometimes, you just need to establish and follow a manageable strategy .. which I would suggest putting the large majority of your focus on bitcoin rather than some misplaced ideas about getting rich quicker through gambling.
Of course, you could also play your cards correctly on some alts, but the safer long term bet is likely to figure out some kind of dollar cost averaging investing into bitcoin (and attempt to be reasonable rather than fantasizing about getting rich quick with some manipulated alt).
