The first 20 on the coinmarketcap list are already accepted by the world and have not empty words and ideas. They will be the most perspective in the future.
No doubt Ethereum has a lot of investors and they are supporting it with full effort, as we have seen in many places Ethereum is getting huge potential and value but I have some different thinking that bitcoin is above ethereum as it has more feature that Ethereum and bitcoin has more investors than this, for me bitcoin is the coin that has best and bright future in this era. It is safer than other altcoins and bitcoin has a lot of wallets so we can save it fearlessly for long time to get safe and bright future with bitcoin.
