Lifting a ban is not enough to bring the miners back into the game, it is barely making money in the USA unless you mine one of the altcoins instead. Good news for future miners though
Very true, the only way miners cab be attracted is if it'll be profitable for them to mine bitcoins, lifting the ban is just the first step, the price of the bitcoin is the other factor that can bring back the miners to mine again. And with this current bearish market and the cost of mining in the US, I doubt many will fancy their chances
