The five Nobel Prizes are awarded for outstanding contributions in the fields of physics, chemistry, physiology or medicine, literature, and work for peace. Bitcoin is not an outstanding contribution in any of those fields, and therefore Satoshi does not deserve a Nobel Prize.
When the Nobel Prize Fund was created, there was no cryptocurrency yet. So it doesn't fall into any category of Nobel Prise awarding. If bitcoin serves the interests of Nobel Prize, the foundation should consider to add this category.
There is zero reason to create a special category for cryptocurrency ,its contribution to humanity is moot at best regardless of the the sentiments on this forum.
