not a scam really, just not a fair reward system and certainly not anon
The instamine gives a huge advantage to the ones aware of the bug: Using huge farm at the right time. This is a 2014 coin, these bugs were fixed months ago at this time. This is likely a bug set on purpose.
In what way is it unfair?
Giving free coins using the masternode implementation for some, and high expensive coins using the POW, generates an unfair coins scattering process; This is a way to scam the miners, and investors, like a 'premined' situation. A lot of miner aware of the situation have dumped their coins... This is a very bad move.
If it is not anon, then there is no point for it to exists.
Better algorithms without the issue describes above existed already.
Isssues after issues we can state, this is a coin to avoid.
