Invested for level 4.
From my calculations ~5 days till I make back my BTC.
For level 4 the sht fills up every 3hrs and 45 mins. Meaning there are about 6 collection times in a day.
24/4= 6 (I rounded 3 hours and 45 to 4hrs)
Each collection is = .009 BTC
I plan to do 5 collections per day since I have to sleep and I ain't setting an alarm up

.
That equates to about .045 per day! Meaning in ~5-6 days I will have made back my .25 BTC.
Wish me luck guys
