I am using ETH as payment for transaction costs, and I have absolutely no intention of accumulating ETH in order to profit from its increase in price. In my opinion, ETH was born to be used by users of the Ethereum platform, which makes it the top altcoin.
However this position is threatened by TRON, Cardano & Polkadot. As a fan of Ethereum, I was really scared by Polkadot's development.
