And down the conspiracy theory rabbit hole we go! I love your theory, and it's very plausible. In a way this just boils down to "was the money 'good' or 'bad'?" and "will the money be used for 'good' or 'bad'?". It's fun to speculate, it's best to know more of the truth.
My hope this will blow up a bit so we get more information (it's in the public's best interest to know more). This is the way all "conspiracy theories" should go, at least those with credible theories to test.
If the totally unsupported claim that it was dirty money in the first place, it makes even more sense to spend money to become legitimate himself. The only evidence was his last name, no idea if it's common, is shared by someone who is claimed to be a drug kingpin in an online article.
Certainly a rich young man investing in something he believes in sounds more plausible than Reddit cooking the books and doing so in such a spectacularly bad way.
