And where is the 21 BTC now? 
- I think you know the answer. I am sure, they are spending on exchange creation, on rewriting Nxt networking, maybe on blockchain explorer, and so on. And 21 BTC is not comparable with 4000 BTC Mastershit Exodus.i am coding the blockchain explorer without any payments during my spare time
and i don't ask for money. if the explorer is finished, rocksolid and usefull, the user
can decide to make a donation but i don't depend on this. the explorer ist more a
testbed for larger builts like additional exchange services for the client etc.
so i would write the explorer anyway
