It's not that people are getting tired, it is because exchanges are not allowed to have  privacy coins such as XMR and Zcash. Obviously those coins functions are to obfuscate transactions. And with the recent FATF rule, it will be hard for this coins to stay in crypto sphere because they are being used by bad actors i.e. criminals, terrorists, drug lords, etc. Low volume is just an excuse for those exchanges to delist them, just saying.
