Upgrade to lower block reward of 1,000 NYC and implementing annual Jan 1st New Year's halving thereafter will be a very simple, straightforward upgrade.
However, implementing a POS from an original POW coin is very difficult, very time/labor intense with many potential pitfalls that is beyond the resources available in the NYC community at present.
Okay, here is my 2 cents on this matter, #1 issue to me is, I thought our votes were gonna count for something, or why waste everyone's time. This statement quoted above, is definitely not gonna help this coin. The reason being, Look for instance at HeisenbergHex Coin, max 23 Billion coins, and the halving started way, way earlier in the block chain than this one. Here is a link to compare: https://bitcointalksearch.org/topic/annhex-heisenberghex-too-many-cooks-spoil-the-broth-un-updated-502589, and you can't give away HeisenbergHex, I've got millions of them and they are listed in several exchanges, if there isn't gonna be any REAL change to this coin, then why waste our time? 100 billion, and just that little change that you suggest, sorry, but, NOT gonna work.
If you need funding and are REALLY gonna make the changes voted for, then speak up and find a way to get it done, tell us the cost, and see what can be done, don't just give up.
Who knows how many of us might chip in? I'm willing, but not without REAL CHANGE.
#2 Whatever you do, just be completely up front and honest with us, and we can make this into something great, otherwise, I've already invested enough time and effort, because it will never amount to a hill of beans. 100 Billion with No Real Changes will not work.
Anyway that you choose to look at this,...... there is only so many things that can be done without losing trust, you can't go backwards and change the total amount of coins to millions, without losing all trust, because Billions have already been mined, that only leaves 2 options...lower the Billions to an amount that hasn't been mined already, which will require the same DEV wallet $ to change the specs, as the amount you say we can't afford, or change to POS specs like everyone is in favor of, according to the vote, and find a way to fund it.
I would rather take my chances on helping to fund it, and make something worth putting some effort into, rather than put a whole lot of effort into something friv·o·lous. "not having any serious purpose or value."
