Are not all types of crypto or altcoin that operate in the market are very influential in their mobilization of investors, if so I speculate the current market conditions are difficult for Investors who believe in Altcoin, investors have been deterred of fraud cases that occur in the market against Altcoin.
We understand the current market situation, investors only focus on Bitcoin, so it's hard for Altcoin to move, not surprised that many famous exchanges remove new or old altcoin, because the cross volume is less than almost non-existent.
There are thousands of alts in the market with each alt claiming that it has novel features embedded inside and is best utility token. But in reality only handful alts have given good reward to their investors while majority failed to take off due to different reasons. In past we saw alts prices were tied with Bitcoin price moment but now investors are solely focusing on Bitcoin and that's why there is not much rise in price of alts despite Bitcoin touching ATH. The primary reason for this shift towards Bitcoin is that if Bitcoin governs the price of alts then why not invest directly in Bitcoin.
