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
Because they are not popular.And only bitcoin and Ethereum can be convert into any FIAT.If the demand of anything is more,the price of transcation will be more for sure. You can use the cryptocurrency to inverse your money and get profit from it.No currency will replace the bitcoin and Eth.
