Phillip, im still minig SIGT, because the profits have been super stable for me, i am making more off the sellings daily than mining another coin... Sigt tends to fluctuate SOOOO SOOO much on 99% of the days, so since im averaging around 1500-1700 coins mined a day with my rigs, i have been selling them daily and setting a auto buy order for 10% of my sell price, i have a built up list of these buy back orders and im still getting my daily BTC payout, because im not holding the SIGT coins daily really, remember i sold them for BTC each day, then tied that BTC up for another buy in for a guaranteed 10% profit if it ever does buy back in, i have a few of these pop off throughout the week.... so im cashing out my SIGT i mined for BTC daily and probably making 10-30% off that balance in week if the movement dips low enough...

I am staking just over 200k in SIGT, but most of those coins were bought back at 50-90% of what i mined them at.. basically increasing daily payouts by %.... i tried this on ZEC and LBRY, just not enough movement to get more than 1-2% out of each trade... so i have been sticking to the SIGT coins for now..

If i ever need BTC, i just go cancel some of the older orders that i placed that have not fullfilled and im instantly liquid back into btc...
