Do they make sense?
Israeli blockchain start-up Colu launched a new e-currency in East London for the local economy, according to Crowdfundinsider.
I absolutely find them useless. This attempts has nothing to do with decentralization as long they remain local. We already have local currencies as paper money.
Perhaps they do make sense as an attempt to get a compromise between fiat (fully centralized) and cryptocurrencies (decentralized). Cryptocurrencies areproducts of globalization but along with globalization usually occur some localization processes. Thus, eventually, globalized product has to adjust to local culture and as a result we get a thing called glocalization. Local cryptocurrency implements IT into the state, so I guess it is a nice try.
