Looking at the present situation of the market, it will be a better choice to hold on to your usd or stake it somewhere or even lending is a good option to increase your total value. Alts are not doing well and BTC is going sideways so be cautious about any trades.
I feel that the current stake is not an option if he plans to hold it in the short term. I might prefer to hold on to popular altcoins like eth or bnb. however, current conditions are still difficult to predict. it's just that, currently the price is relatively low, and maybe it could be an opportunity before the price goes up again.
