There are plenty of calculators out there to answer your questions
I don't trust them. I keep getting different results. Some say yes, some say no.
If you dont trust them then it means is out of your league and if you dont think is out of your league then by all means you should try yourself, check your hashrate and difficult and mine using different pools and maybe by a miracle even with all the results from all of it you will believe in yourself, i'd say you have problems with acceptance using facts.
Decred like all the cryptocoins, is not profitable and for it to be profitable, cryptocoins should have at least 700% increase in their prices.
Thanks, I'll keep that in mind.
I think I will go for the Innosilicon A9 ZMaster, that will net $5/day after costs. It will be an enjoyable little side hobby. I already know I'm not going to make serious money, but pocket money is okay for me at this point in time. It's a passion of mine so as long as I don't lose on electricity I'm okay with that.
Edit: I did manage to check the claims of the A9 ZMaster, buy asking a friend to point a few minis for 50k/sol at slushpool. It seems to add up, so I'll take that risk. The ZMaster is super efficient too, 650 W or something like that. Half a Bitcoin miner in electricity costs. I can't seem to find anything that's profitable for Bitcoins directly, even with the bigger higher hashrate machines coming out. But converting zcash to btc would be an option, same for just holding zcash that I can mine, it's all a bit of fun, and if it goes up in price, well that's great. If not, that's fine too. At least I can hodl some zcash, maybe mine some alt-coins with same algorithm.
