Currently 3x1070 with OC makes 5000 coins per day (suprnova) - it's less profitable than zcash
5000 * $0.001529 = $7,645 ($2,548 per card per day)
zcash is only around $1.2 per card per day
You're right, my mistake in calculation.
Does someone know about situation with XCN wallets at the poloniex? disabled now
