The role of public figures is indeed very helpful for the growth of the popularity of cryptocurrencies, especially if they are willing to promote it every day, then this can certainly encourage many people's trust in certain cryptocurrencies such as bitcoin to become stronger, thus creating high demand and making bitcoin more valuable.

If you remember ews of Elon Musk with support for crypto currencies and bitcoin had a good impact right ? on the crypto community and bitcoin price. which becomes a bad thing only when he supports doge and people think he manipulate market prices. so I think when there is a public figure who has an impact on an economy supporting crypto / bitcoin in real bussiness and open about it. it will definitely have a good impact on crypto.
