I think reactor is a very bad idea. It will increase the investment and not the commerce which means it just helps increasing the bubble. Every investor wants a minimal profit therefore they have to sell some amount of dmd. It will destroy the exchange rate. You really want 1-2 winner and everybody to lose?
You have to establish an economy behind dmd.
So you don't think the reactor will strengthen the economy, just as the cloudmining did?
It will not strengthen the economy due its nature, just like PoS. Cloudmining helps to link the exchange rate to other coins and bitcoin which is helpful because you can't establish economy if ex.rate is unstable.
But staking only prevents the mass selling and does nothing more. Reactor is an other method to hold the coins(maybe more coin than PoS) while it extremely increases the number of coins and decreases network security because you have to hold lot of user's coins at _one_ node.
If there are no economy(=trading goods) then your coins value will be based on a bubble.
This reactor looks like the gnomes' plan in south park:
1. get dmd
2. reactor
3. ? ? ?
4. profit
