i agree! mining ETH yourself is the best chance to get profit out of it. atm i run 15 Rigs at arround 1850 Mhs that give me between 10-11,5 ETH a Day. At the same thime this Rig's mining also DCR and HOdl Coins. if i sell this DCR and buy ETH for it, i have about 1-2 ETH a day extra ;)
HOdl Coins are not worth it to sell atm but u can mine it with CPU and this little more power consume from the CPU doesent hurt. Maybe they will be worth more some Day :)
Happy mining!
