Why are there so many coins that have higher transfer rates than bitcoin or eth, and the fee is also cheaper than it is for increasing transfers, but I feel like more advanced coins are getting worse. . Is it now that cryptocurrency is just a place to invest and make a profit without seeing its power and meaning? I think better things will replace the old ones
It will be almost impossible for any coin to replace bitcoin and no matter how slow bitcoin transactions is it has established strong foundation in the mind of people that will keep it forever with us. We can used bitcoin for many things including as a stores of assets and i do believe that is why it is very expensive.
They can't replace Bitcoin even if there were too advanced, those newly made coins will not gonna step on the level of Bitcoin. They will always belong to the altcoins category. BTC and ETH are the two great cryptocurrencies that we could trust for the rest of our life. People will always choose what's the best for them and not the hyped-up coins which have nothing to do in the long run.
