The difference is gray, but in theory the politician's causes can be supported without direct financial gain to the politician. They are the same thing in the end. Power, money, influence, information.

Insider trading seems to be one of the more common bribes and as I understand it's legal for congress, which is a huge problem.

Bitcoin is the ultimate bribe tool. A politician can be handed bitcoin in a way where they can verify that they own it, but no one else knows.

As a result, bitcoin will compromise the entire corrupt structure and take over the incentives.

This will also work temporarily for the shitcoins, but the real value and attention will converge on the best asset in the end. The most saleable will win.

Ultimately the issue is not the ability to bribe a politician, there will always be ways to do favors for influence. The issue is that any individual can have such massive amounts of unchecked influence and utilize it to control others. The smaller the government the less corruption will exist.

Bitcoin will accomplish that in my view.
