1) It depends on whether the mining reward is treated as compensation. It probably should be considered compensation, in which case it is taxable ordinary income when received. However, on a subsequent sale, it should be taxable gain only to the extent that the sales price exceeds the value already taxed as ordinary income.
2) If the value of BC crashes between the time earned and the time the tax is paid....then yes, you're SOL and still owe taxes on the value of the BC when received. However, usually there is a corresponding deduction to help alleviate that.
3) Pool mining almost certainly is taxed differently, since it is more akin to investment income than to compensation income.
