Elon Musk has indeed made Dogecoin popular, and made Dogecoin the best trend in 2021. But what he did disappointed many people. Especially investors who hope that Dogecoin can be used for transactions at Tesla, while the application is not the case. He returned to Bitcoin, and left Dogecoin for now.
But if you're hoping that Elon Musk develops his own coin, it probably will. Even if you want now, you can buy Telsa shares on Binance.
