So we only can make profit from CPU mining if we mine coin with cryptonote technology? What about another coin that does not have privacy feature? Can we still make profit mining it with CPUs?
You can mine another altcoin that is not including on the crypto night family like dogecoin, ETN, XDN, etc. But remember you can only make a few cents in a day and you can't put a high expectation to earn a huge profit.
Those coin I have mentioned above are not cryptonight coin.
