That's actually a smart move for that altcoin creator, to entice the people into buying his product because he sponsored/bribing a presidential candidate.
I guess, it won't be "happy" anymore if this candidate wins and promote his coin as way to thank him for the sponsorship he's done during elections, then eventually the creator of that coin decides to dump and gradually exits the market after he hits his target.
I would guess that the president wouldn't care at all, and neither would the coin creator neither. The amount however is quite tiny, is that a lot of money in Nigeria? Don't get me wrong, that is a lot for regular people in most places, hell in the USA which is seen as a rich nation, people make about 5k per month on average, and that's average, so there are tons of people who make less than that, some live off with under 40k, meaning this is nearly half of their yearly money.
But, when we are talking about a presidential candidate, in most nations there are a ton of donations and a ton of bribery and corruption, so we never really consider 0.55 btc as a good deal.
