man, is it ethical and you use this for ICO??
We found two big problems: On the one hand, an excessive (more than 20% of the supply the first four years) "founder rewards" to private investors and on the other his disastrous mining solution, not only by the slow start but because a few private investors have access to exclusive gpu miners, which are to ensure them the vast majority of the coins created. While other users will be content with an underperforming CPU miner. So, the private investors are only attracted by quick profits and will be the first to dump his excessive amount of coins to investors attracted by the technology presented for Zcash.
These two issues affected and continue to affect the state of zcash. That is why we want to offer an overcoming proposal without these problems.
