Considering in 6 months ETH will be unmineable and the rest of the coins will remain extremelly unprofitable due to difficulty, you have to be really dumb to start mining at this point.
You will probably not even be able to ROI your equipment in 6 months, and more than likely you will have to sell it at half the price you paid for it if you need the money.
NEW MINERS are the NEW MORONS.....
What difficulty you talking about? In 6 months time mining will be less profitable and many miners will shut down their rigs or you don't believe we will be in bear market at the time? Here is the catch you can mine more coins in bear market than bull market, for example if your hashrate is getting you 1000 ravencoin per month now you would make 3000 per month in bear market due to less difficulty, many won't be able to pay for electricity costs anymore
