I turned on staking today and within 10min I got 40k coins. it went to 80 days to next and at 39 days 6 hours later
You get those stats when you move mouse over the staking icon. It gives you estimate of next stake.
I my case after the stake it recalculated and came up with 80 days for next state.
6 hours after the sate I checked the stake estimate and it said 39 days until stake.
So in 6 hours I went from 80 to 39 days, which means that it goes much quicker if it passed almost 40 days in 6 hours.
Coins have to in the wallet for 24 hours before staking.
You can barely see the staking icon. (I hope that it will be more visible next wallet release) but if you see the lock icon on the bottom left corner. The staking icon is immediately to the right. It wont say much unless you're staking already.
What miner do you have for solo mining? I don't think it's a good idea.
You'd be best pointing your miner to Nicehash and then using BTC you earn to buy LINDA.
As far as mining goes... I own several L3+ ASICs and was trying to mine LINDA at H2C pool which is not as profitable as, like you're suggesting mining over at nicehash and buying coins at an exchange. Problem is, mining at nicehash is not the most profitable solution either )), which made my thinking about setting up a solo mining setup to see if I can mine more coins as compared to H2C pool plus avoiding hassle of dealing with exchanges.
