BTC and blockchain are a new round of technological revolution!
BTC will not disappear, and those that disappear are those that are not used as speculative wages for speculative wages!
ETH, EOS.ADA.OMG and other cryptocurrencies will survive with BTC!
Yes both are revolutions and both came into light at same time.
ETH,EOS,ADA are blockchains by themselves and many new blockchain projects based on them.ETH blockchain provide platform for new blockchain projects.Is same case with Bitcoin??? As much as I know Bitcoin is a payment network and first digital currency.
