Keep holding your Ethereum, all those tokens you mentioned aren't that good, if it's a must that you want to buy another token you should do research on Chainlink, this project never disappoints due to its usefulness, it's the king of Oracle data today
Link is a good coin and that's pretty self-explanatory in my opinion because by the time there's a pump in the market, Link looks to be improving well and also very consistently, so obviously not a bad thing to have, neither does Ethereum.
