I first heard zcash has a new fangled alternative to POW and POS that was touted as assisting decentralization. If GPU mining it through pools has given one pool over 51% of the mining power the new algo hasn't helped decentralization at all.
Devs made all possible to achieve such a situation. No GPU miners from devs, no Windows wallet from devs, no p2pool nodes available to end users (I mean miners here)... Looks like they don't care about decentralisatiion. They care about 20% of coins for 4 years.
Exactly. All of your points mean decentralization and good distribution is far from being their priority.
In fact, I find it ridiculous and I have never understood why major coins would ever get released without linux+windows+mac+android wallets and AMD+Nvidia miners?
Even most shitty scamcoins are doing a much better job at that.
