most people think that "No useful Dapp or any sort of business based on bitcoin or crypto in general that is making a decent amount of revenue except for exchanges and mining hardware companies.!"
nobody really thinks that except those newbies who are bag holding ethereum and are brainwashed into thinking DApps are actually needed for a cryptocurrency! and have forgotten that a "currency" doesn't even need that. bitcoin is designed to be a decentralized currency and it is just that and is doing a perfect job with all the attacks so far.
