I will be more impressed if he do it on regular days like there's no election coming. Since for what he did its like he just wanna sell out those things what he do to his bitcoin then gather lots of exposure or create some impression that he's really supporting bitcoin. But since he do it on these days which he need votes of people so provably that this kind of actions is just for his political exposure.
He provably want to be visible to bitcoin user and show something that he use bitcoin then would provably support it under his term. Although this is really crazy but let see what will happen next to it since for sure we could provably see more of this kind of act especially election day in US will happen in November. So politician will double their efforts to convince people to vote them.
If you were a businessman or politician, I bet you would do things like him or like other celebrities. You will always take advantage of every opportunity, anytime, anywhere in life to attract crowds and benefit yourself. You can only stop doing those ridiculous things when you have achieved your goals.
Likewise, why do I, you and everyone invest in bitcoin? We will not use bitcoin, will not support it to become more popular if it does not bring us any benefits. Humans are like that, they only support or care if it benefits them, otherwise no one would spend time and effort focusing on something without expecting any benefits.
If they do not use tricks and take advantage of every opportunity and participate in the election in a transparent manner. Those people are not politicians and can never win the trust of the people and win. Politics is like that, lies, tricks, there is nothing that is not dared to do as long as the goal is achieved.
