Time-lock rewards as well as Harmony mining are still very controversial with the core developers and mining community.
The gate that has passed (as far as timing) is choosing the initial feature set for Blossom upgrade. It remains to be seen if Harmony mining & Time-lock rewards will pass Security and Network stability audits.
I hold a few cryptos as a speculator and to learn the tech.
I like that anyone who mined in the last year has a vested interest in ZEC succeeding. I'm just not sure what they could do to improve the price. I'm confused if this makes mining centralization worse or better. At least one comment made me wonder if this will push out big pools in favor of smaller miners.
Other posts argue it will kill smaller miners who don't have cash reserves. I don't know if I believe that. Since they are GPU miners, they can switch back and forth between ZEC and another coin to cover their costs and build up their ZEC payouts. So I could see smaller miners easing into it. Could be insecure though.
Will be interesting to see what happens.
