I maybe could even BET that Cryptopia won't release its wallets before PoS begins, exactly like I initially told.
Also mining didn't turn any profitable. At the beginning of September WhatToMine-church was telling SIGT to be $20/day per my 1080+4x1080TIs rig. Mined for a week (7 days straight) at 230mh/s - got 2000 SIGT, worth $50 (but should got $150 if it was really $20/day). And now it also fell almost twice. Not worth mining at all. I assume WhatToMine is also getting paid to promote SIGT on the first place, tweaking a couple of numbers. Like Craptopia is being paid by someone for holding the deposits until PoS.
Btw, last deposit was 30/08/2017 10:09:00 PM.
If they claim about 3 tx/sec - they should have a very crappy internet on the island...
For SIGT I found their calculator pretty accurate to be honest and it is profitable for me at least. I'm running 7 x 1080ti's and at about 1.75kw/h (£0.114 k/w or $0.15 k/w) total with about 380mh/s, I'm still making a profit. I could make a bit more mining ZEN or ZEC but making the most of these last 16 or so days mining before POW ends. Just wish I had got mining this coin sooner but had other commitments sadly. Personally I think the mining pool can have a big effect, I found suprnova poor for this coin but good for ZEN.
To be fair I would obviously have to include the hardware in the mining cost but I will have only been mining it for 20 days by time POW ends so it's a small percentage. I'm factoring those costs into my other coin mining and before the Chinese made a mess of things ROI was around 12 months.
