I want an answer please ..
Do profits are the same or change in level 2 .exp: if invested 0.005BTC configures as if invested 0.007BTC at the same level??
Level 2 costs 0.005 BTC or 500000 sats . For this you get 70 sats per minute for 10 days = so the maximum you can earn is 100800 sats per day x 10 = 1008000 sats or 0.01008 BTC. However your building only has a capacity of 15000 sats which means you'll have to claim 68 times divided by the number of days is 7 times a day (every 3.48 hours).
You can't invest 0.007 BTC at level 2, the next amount you can invest is 0.01 BTC
