1. Money laundry; they are the preferred choice of criminals;
2. they’re primarily speculative, work as a pyramid scheme;
3. it is subversive, negates the quintessential aspect that currencies are brought in circulation by authorities which can be held accountable;
4. the mining has the energy demand of medium-sized nations;
5. conventional currencies are actually like a fine barometer for a country’s financial and economic situation.
