Don't be naive to think they are pro-bitcoin.
That would be unwise of me now, wouldn't it? because the fact that he used Bitcoin as a platform to amass support tells me the kind of person he is; a businessman who is unapologetic about whatever means he uses to gain profit. At least he's been open about his actions.
However I would not call him pro bitcoin what I see is more of a business man using Bitcoin as a platform to gather attention support and profit that does necessarily mean he truly believes in the principles behind it he just knows it is a strong tool to get people on his side.
And honestly that is how a lot of business minded people operate they all leverage whatever works weather it is bitcoin today or something else tomorrow at least in this case he has not really tried to hide it he is open about using it for his own gain which tell you the kind people he is .
He is pro-profit, just like the rest of them.
He just sees in crypto what can bring him results.
