I'll give the DEV the benefit of the doubt in terms of "scam", however I can't ignore the fact that this is simply not going to work in it's current form.
Regardless of if it was lack of planning, or if it was a scam or malicious act, it's evident that the average joe with a decent GPU simply isn't going to mine anything here.
Up until the 1 off lucky block, the 9th guy on the rich list had only mined 0.00000517 LUX in all his mining time.
Compare 0.00000517 to the DEV's 3 Million coins (that as described are compounding massively with staking), and you have probably the largest inequality between Miners and DEV I've ever seen.
Even if I run my machine for years, I'm going to end up with something like 1 LUX coin. It's just a broken system.
As said above, Im not calling the DEV a scammer, but the coin distribution is completely broken here.
I'd recommend some sort of relaunch, with perhaps a bonus for the lucky few who got 10 coins in the lucky block as compensation.
