as far as I know, Bitcoin is the king of cryptocurrency. Ethereum is like a bitcoin boy. ETHEREUM has a number of altcoins that use their platforms a lot and it shows its strength. this is very potential and they will continue to grow strongly. if the ripples have received recognition from many financial giants. Although I do not like cryptocurrency that is too centralized, it violates the initial goal of decentralization, but in terms of investment, centralization may be more promising.
