I will never sell ETH to buy Solana, I prefer to hold ETH over Solana, although at the moment Solana looks convincing but I am sure that ETH will skyrocket again soon and the opportunity to become the king of cryptocurrencies replaces bitcoin.
Holding ETH is not wrong and is still in a very good category for anyone, but if you expect ETH to become the king of cryptocurrencies and replace Bitcoin, it is a dream that will be very difficult to come true because when Bitcoin started to fall in the market, ETH was still experienced the same thing, meaning that ETH still often follows the cycle of Bitcoin conditions to date, so there is very little chance of becoming king in cryptocurrency.
