If we are talking about our global altcoin season, I do not think ETH 2.0 will bring much impact into it because the upgrade is specified as a transition not an innovation for our global technology in the blockchain. Unlike before, when ETH brought us smart contract system that helped us greatly. On the other hand, even though this ETH 2.0 does not bring that much of impact on our global market, for itself is a huge boost. Because the only way to get a new coin is by using staking, that means the demand will increase.
holding it is preferable, but of course, everything is possible. As long as you can afford it, why not?
