That depends upon your point of view, dude. Recent difficutly and total hashrates almost trippled after Bitsum listed on its first exchange. However, good news for you is its price has stayed really low. Is it good signal for traders?
Furthermore, as a miner, you should learn, observe the difficulty-hashrate cycle and their mutual relationship. More time you spend for mining, more experience you get and you might be smarter (just might be).
Do you think this is a good time to mine? What do you think about the new cryptonight asic coming out from Bitmain?
Not now. You should mine this one two or three months ago. It is not profitable at the moment.
