What do you think the twin will ask from Trump once he wins? It seems to work that way in politics, they won't just give some thing without expecting in return. I think the more crypto big names donate to Trump, the more he will have a huge debt to repay the crypto community.
If Larry Pink will donate more to Trump, then Larry may have all the favors and god knows what the guy will ask from Trump.
It's difficult to say, all these things happen behind the scene. They may just want some lobbying power in the future for a lot of things that may not even be related to cryptocurrencies. But they definitely want something in return which is why I wouldn't use the term "donation" to describe such payments of this scale by such people.
