ATH of ADA was $1.33 on Jan 04, 2018 that is 3 years ago. After 3 years, Bitcoin and few altcoins hit ATH records. So why not possible for ADA. It is possible but we increasing demand of ADA will push it to the uptrend next. Many investors are staking ADA in wallets, it releases sell pressure that can also be positive for next bull run of ADA.
