Absolutely!
In my opinion, in bear market, if you can find coins that can give you enough income from mining to pay electricity bills, and of course have extra coins to hold in your wallet.
They are perfect coins to mine, because holding extra coins after paying electricity will give miners bigger profits later when bull comes.
Mining a coin now has a bit disadvantage due to bear market. Imagine the expenses you incurred from energy and electricity just to mine out few coins.
Can you give me link to the topic of Taucoin, please, Tipster.
What the best one Im eyeing is the taucoin project that developing a solid mobile mining application.
