I know so little about blockchains especially ethereum
Some say ethereum is fully decentralized
And EVM compatible blockchains like Binance Smart Chain
Polygon, Avalanche and Heco are not as decentralized as ethereum
But their gas fees are cheaper but
I do not know the differences between these networks
But they are derived from ethereum I think
I do not know whether they are modified version of ethereum or not
I think someday they may fade away and disappear
My assumption may be wrong as I have little knowledge about them
But I cannot use ethereum blockchain as the gas fees are too high
No matter they are decentralized or not
I mostly use BSC chain now as it is cheaper and
There are many dapps on BSC chain
