What real value has been produced in this system? Bitcoin is still as broken as it ever was. Ethereum has spawned 3000 ponzi schemes and maybe half a dozen contracts of real use, all of which are miered by the oracle problem. The eth network has about 10,000 daily users, which is pathetic. XRP has failed to secure the ODL flows it promised, and failed to secure banks actually using XRP in remittance flows. It has some small flows from some remittance companies in some corridors.
Three years and countless millions of dollars "invested" and we have 3000 vapourware projects and the non-vapourware projects have been little or no progress.
