The best crypto to invest in conversation picked up a fresh signal from DeFi’s largest lender after Aave launched Stable Vaults, a fixed-income product that lets wallets, exchanges, and payment apps offer yields on stablecoin deposits, according to CoinDesk.  AAVE jumped more than 6% on July 10 while the total crypto market cap just climbed to $2.31 trillion as risk appetite returns. The two categories behind the largest crypto fortunes have always been presale entries and meme communities, and right now one token is carrying both of those engines plus a third that has never been combined before.
