If you have enough assets such as capital, mining tools, miners, etc.(can manage small businesses)
and also you have a small private block-chain system.
until now, you have mined 10% of the P-coins(new Bitcoin, not the Altcoin) with your partners.
and you are preparing to open the Bitcoin exchange(including of P-coin).
In this situation, It is possible to make a new Bitcoin?
If P-coin is released, how many people will be used it? And can it have the same value as other coins?
Theres no new bitcoin and what the heck is P-coin that you are saying? You said its not an altcoin? How could it be? As said above all coins that's not bitcoin is really considered as an altcoin.Period.
You are asking nonsense thing here or just advertising your coin? P-coin? Didn't heard such thing as of now.
