Ok usually I say to save things because it's useless to mine btc if you have no faith in btc...
But let's get it right, right now it seems logical to sell a big part of it, or at least transform parts of btc in altcoins clearly!
I don't think selling now can be good decision as the price so comparatively low at a moment, its better if we save now and sell after the halving when the price would be better.
Yes, and I don't think that mining can be profitable with this price, its better to buy and hold it for few months, so you can sell it at the higher price at the time of halving.
