Cardano is leading a sluggish comeback in the crypto market ahead of Memorial Day. On May 16, ADA was one of the best-performing digital assets. The unveiling of the Alonzo smart contract testnet by Cardano's development team, Input Output Hong Kong, or IOHK, is being celebrated by ADA fans. On May 19, the cryptocurrency temporarily breached the oversold indication on the hourly Relative Strength Index before strongly rebounding over the following 24 hours.
