If you believe a project has real value and that the token will appreciate in price during the lock-up period, then by all means take advantage of the higher yields available through locked staking. Always be aware, however, that prices can go down meaning that, when you unstake, the coins you bought, even with the interest they have earned, could be worth less than you paid for them. To mitigate this risk, think about staking stablecoins such as UST.
