#1. reading more about hybrid coins...like Decred.org and PoS,

i think my method is better...
https://bitcointalk.org/index.php?topic=2372215.20

technically, more complex, but giving reward to Nodes without coins is more important, than giving coins to Masternodes...
Masternodes reward incentivates a 51% attack.

the Problem of PoW is a 51% attack,
the problem of PoS is Nothing-at-Stake...
https://en.wikipedia.org/wiki/Proof-of-stake
https://docs.decred.org/mining/proof-of-stake/

but giving rewards to Empty Nodes in PoW mode, incentivates 51% attack free environment.

PoW also has flaws.

Decred has Blake2 algo but the only argument is that is faster than sha256 in smaller block sizes & more secure..
how fast? 10%? 20%? 100%?
only downloading the wallet and comparing similar network load could reveal the answer.

Master-nodes are needed for coin mixer, but it´s a form of centralization.
Centralization = Bad.

#2.
yesterday was trying to install xmr-stak-osx pre-compiled in OSX,
it needs to install a lot of libraries, and optional software,
but did not work, a library.5 was not found on the system,
mining software is very sensible to OSX version.
similar to Linux, is not worth the effort.
