Snoop Dogg invested in altcoin and not Bitcoin and he also has his own NFT, generally, this will give cryptocurrency a wider public awareness and also mainstream media. Big names invested heavily in cryptocurrency this year.
Well the title says clearly , "13 top celebrities adopt CRYPTOCURRENCY in 2021" meaning there had been mention nothing about Bitcoin literally(though this is a Bitcoin discussion board) so meaning even in which currency they invest , Bitcoin,altcoins yet they are investors and adopters .
so basically Snoop Dogg like the other rapper(that i forget the name) is crypto users and investors.
floyd mayweather, mice tison, i saw on his body there is a bitcoin tattoo, i'm sure he also invests in bitcoin, and there are other names too like famous footballers like leonil messi, messi is one of the most famous people in the world, he once posted about blockchain on his instragram, he even talked about bitcoin in the media..
I guess it is Mike Tyson that you mean?
but since they have tattoos in their Body so more or less they are crypto supporters .
