They're actually both good for investment yet they aren't worth buying this season. We're in the bearish market and we don't have assurance if these coins would survive. I could see that Sandbox has an edge but if you would risk your funds, better risk it with potential and profitable top coins or better yet Bitcoin and Ethereum.
Both coins are unworthy if compared with bluechip coins, but in my opinion they are still promising. Both can be classified as risky portfolios if you are a risk taker and enjoy predicting market trends to take advantage of the best market opportunities. Metaverse is considered the main trend of the upcoming bull run so investing in these 2 coins is also worth considering although the risk is there.
