If there would be a method to block big miners would you be willing to use it ?
I don't think that it's necessary to block large miners. First, as practice, this is almost impossible. Second, we have a better solution - a special reserve will be allocated for large miners in our pool. This will leave us control over the network power and will not allow an attack 51%. But everyone, who is mining now from the very beginning, will not care about the presence of large miners if the price of the coin reaches at least $1000.
I thinks it's easy to block big miners.
Also if you want to have many users it's important to do so.
Nobody is interested to mine BTC or other other coins that are controlled by a few big boys.
Allowing big miners will kill this coin maybe within days or some weeks just like any other POW coin.
As you know mine and dump.
$1000 per coin
At best you will see a spike when trading starts.
