From coinmarketcap.com we were able to get the top 5000 currencies.
From those there are 3864 based in other currencies like ETH, Cardano, etc.
Here is an overview:
Most of the cryptocurrencies are made based on Etherum, from those 5000 more than a half 66.5% (2569) are built using ETH.
Then, the other most used platform is Binance. Both platforms hold the 2nd position: Binance Smart Chain and Binance Chain used by 935 and 61 respectively. Binance Smart Chain support smart contracts and Binance Chain don’t.
This is the break down:
There are 707 coins that dont depend on other platform with circulating supply with price < 1.
