Not sure if it will accept my post of your link better. BLK has been going since 2014, its not just anything its many things and its still being developed. Theres no reason to draw conclusions from just the first six months because BTC has gone down since December. Sure that decline sucks and that bigger influence knocks onto the small economies like BLK and every crypto coin but its still here working away just the same as previous years and it'll keep plowing forward into 2019 also. Its worth some perservance is what I'm trying to mention, I say that from the perspective of following this project over many years. Its not reliant on any one person which is key to any crypto standard for longterm continuation and success
I really do think this is something. Every day POW progresses they have to resolve this efficency dynamic they have, we dont have this problem. POS wallets will run on anything and I dont need expensive hardware or alot of wattage to power it.
So think of that as a ratio, the prospects for POS are improving this is a very viable long term path where POW must juggle and somehow find a way where it doesnt cost so much to process that it becomes a problem. BLK is super easy, fast and cheap to transact, we have the upper hand on this imo
