One disadvantage of decentralized money, criminals gain more power. Many such cases

There are always complaints on here about how Google is only paying $X for vulns. One advantage of decentralized digital money is that its bug bounties are self funding and the payout amount researcher-controlled.

That is a natural consequence of banks and governments losing power. That power balance shifts towards the citizens... some of whom are criminals.

The coin fanboys will argue that the bankers and government were criminals as well.
