Before, it was for the tech, and to be honest, it was a golden era when people mostly invested in Bitcoin because of its decentralization, and truly in it for the tech. But today, can't deny that most are just interested in the profits, and it's not going to change. Time has changed but those people that are truly concerned about bitcoin's decentralization was still there. Fighting in the shadows and doing it silently. And maybe the others don't care anymore when it's only about the value of it which everyone is looking up to.
