There are many good currency so you can buy dump price.
Yes, there are thousands of cryptocurrencies in the space, but the majority are only shitcoins, and you can likely accumulate a whole lot of shitcoins if you want to invest in Altcoins, unless the person is ready to just risk their funds. Although there is no investment that has no risk, in terms of cryptocurrency Investment, Bitcoin is more appropriate to invest your funds in with the hope of making future profits. I believe that investing in altcoins is only trying your luck because you are not very sure if the project can last more than two years to even earn you any profit in the future.
So what are your thoughts on ETH and BNB or Dogecoin that I think you would call them shitcoins? Those are projects that have existed for over 5 to 7 years and are still developing further in the future. Even investing in them yields much more substantial returns than bitcoin today, not all altcoins are worthless and useless.
Don't be too stubborn to only know about bitcoin and ignore other opportunities. Just like when bitcoin was first introduced, traditional investors scorned and criticized bitcoin and they missed a golden opportunity with it.
