it will take a long time since alot shiba whales quit from this project since robin hood announcement. investors in shiba maybe dominate by retail investors, and too pumped it back to ATH i am believe its difficult thing. maybe need more trigger to return shiba back to ATH beside market sentiment and condition.
And what you say may also be true because some investors also like other types of coins, so they don't just look at the Shiba Inu, even though they also want profit through the Shiba Inu because every good opportunity must always be used as well as possible.
