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.
This is the reason new investor must need proper guidelines before start investing with cryptocurrencies. There are a lot of possibilities for them to get miss guided by scammy devs.
If an investor or a trader could have made a good research first in the beginning, then there will be less chances that they will be misguided in the future. Let's say if they know bitcoin better and know how to acquire them even with just a portion of it, then they should have not resorted into shitcoins that is mostly more on pump and dump scheme. Or maybe invest in those coins that are on top of the market list, i think they will be more profitable in the future than just stick around and settle for those who are only profitable at the present but maybe dumping by the next day.
