Hi, I want to know if there is any cryotocurrency based on Ethereum that today among the 50 best. Creating a cryotocurrency from a contract with ethereum is a good way?
Check out the top 100 tokens at
https://coinmarketcap.com/tokens/ and you will see that 8 out of the top 10 are based on Ethereum. There are plenty created on Ethereum and it is the default platform for creating tokens now.
There are competition from other platforms but it is still the leader in terms of branding and acceptability.
