I'm using a few BTC Mining apps.......all others take Soo long, if at all, to complete withdrawals. This one is immediate! I click the transfer,... It's in my lightning wallet the very next second or sooner. I love the Dashboard and the bonuses…

How do I start mining?
Download the app, sign up with your email and choose the free starter plan or one of the paid plans. Activate your miner and your Bitcoin rewards start accumulating daily.
Which plans are available?
Fixed-term plans of 3, 6 and 12 months with no auto-renewal, monthly subscriptions through the App Store and Google Play, and crypto purchases on b99mining.com/buy with a 70% hash-power bonus.
How do I withdraw my Bitcoin?
Open the wallet screen and choose Lightning (instant, very low fees — best for smaller amounts) or an on-chain transfer (standard blockchain transaction, slower and with network fees). The current minimum amount is shown in the app.
