If you cannot buy 1 bitcoin, then this does not mean that you need to refuse to invest in this coin. You can regularly buy a small part of bitcoin every time you have free money. And perhaps when the price of bitcoin reaches its high at a certain time, you will become the owner of a whole bitcoin.
I believe that most newbies are misguided by huge bitcoin prices and then falling into shitcoins. Yeah, they never realize that they can buy bitcoin even for $50 or lesser than to and they never need to buy one full bitcoins. This could be a psychological approach like you may feel better if you own some 10k dogecoins rather than seeing 0.002BTC in your wallet.
