for newbers in crypto, as for me, safer is to invest in BTC and ETH, if we are talking about long term investment. regarding some profitable tools with good returns i think better to choose credible defi
i'm also newber and try to invest in defi and especially in cool dex projects. i strongly believe in uniswap, and now i consider to invest in stablecoin dex - xsigma. they looks credible for me
