That mitigates these risks for people who are able to have an in-depth understanding of Bitcoin, which is in itself extremely complex and requires tons of prior knowledge. Everyone else has to trust someone with their crypto needs and is left to be fleeced with no recourse at all. As of now, that merely replaces the group that profits disproportionately with a crypto bros and the like.
Crypto Bros are the vaguely defined boogeyman, scape goat, and hate magnet for a coordinated disinformation campagain against crypto .. Are you sure you want to associate your position with that kinda PR?
Don't try to stand up a strawman. The exchanges are manipulating the value of Bitcoin, which affects those not using exchanges' ability to trade at a 'proper' value.
