I have mined Ubiq at start in february, alternatively with Eth : In few days I have found 31 blocks and got 187 Ubiq (it's 320 $ value now !).
See the details here : http://ubiqpool.io/#/account/0xBC3eE8B5D02E36481682C6C9A1fdB666330cf3eb/payouts
I am now using this money to buy some Genesis contracts (uRPBTm). :-)
