Additionally, the coins you named are performing well for themselves in the market and have even somewhat taken over the market. In particular. Furthermore, I have no doubt that some people are profiting from altcoins. And my opinion majority of people that invest in altcoins is because of the money not everyone can afford bitcoin. So and that is why they have give other altcoins but it is still better to do your research.
I know many people have invested in BTC hodling for the price to increase higher before they can sell to take profits from their investment, and whenever the price of BTC is increasing in the market other cryptocurrencies price will be increasing too which is the reason why I still prefer BTC investment than altcoins.
But is not good to make one coin your investment, you can invest huge amount of money on BTC and invest little in altcoins in case anything happen that will affect the price of BTC so that you will have hope that you will achieve something from your altcoin .
Bitcoin acts as a catalyst for altcoins, and individuals are massively investing in crypto in both altcoins and bitcoin. individuals who cannot afford bitcoin will go for altcoins. And holding is for profit, and people are willing to hold any loan for the sake of profit. And there will be instances when bitcoin will rise while other altcoins will fall, and this is due to personal preference, as well as individuals looking at the quality and amount of profit it will generate. However, some people may not perform adequate research before investing their money.
Everyone wants to invest in bitcoin, but money can be an issue. And because everyone has a budget, the best thing you can do is make a sound financial decision for yourself.
