NTDCD was considered a particularly promising avenue of development. Medically speaking it was extremely difficult to perform. In medical upgrades, the promise and the difficulty were almost always tightly linked. Qualifying for such a lavish upgrade required an intimidating level of personal sacrifice.

If it didn’t pay off, then the donor would probably be dead before the funds came back into liquidity.
