If you have a large number of these tokens, which you expect to have a great value in the future, then buying now or in the future will not make a difference, as you will most likely not pay more than $100 Ethereum fees for all your transactions, and if your investment is limited, then buying now will save you a few dollars in the future.
Do not bet on the rise of these symbols, as the market is volatile and these tokens do not follow the pattern of cryptocurrencies with large market capacities.

If I were in his place, I would consider Ethereum more than those fees, at least the possibility of achieving a higher gain.
