How are those issues any different from other currencies or coins? It really comes down to trust and security, which this offers just like others do. At a high level view it's just basically bitcoin but with coins created through externally useful work.
So its just another "better" bitcoin. But bitcoin is already useless. And we already have FBA coins instead of PoW/PoS which are way more efficient. It remove the external "useful" work completely.
