All cryptos are decentralized to my knowledge. These guys are primarily doing ethereum which Is smart. Ethereum has a ton of uses while Bitcoin doesn’t but it has storage value. Ethereum may supersede Bitcoin in market value someday as it has use and storage value. With that said I still own more Bitcoins than I do ethereum but I will not sell any of my Bitcoins until we are past $500k but I will be and continue to buy ethereum on a weekly basis and will one day take over my Bitcoin position. That is why I love this play so much as they are currently doing mostly ethereum
