It was because of the move SHIB did that is one of the reasons why the interest of people into meme coins has increased though I must say that SHIB made so many people rich because I no of people who made huge money from the coin, Doge is also good but in terms of price movement I think SHIB has more than Doge and since then people has always believe that more coins like SHIB still exist and that's why they keep investing on alt coins, I'm not against it but people should always be cautious about there investment.
