35x2 Ads + Removal from PlayStore.
At first watch 35 ads for small amount of bitcoin (10sats). Which was withdrawable. You could buy packs (miners) as well as one time investment. But Later they added offset in which there was no mention of this before buying packs. Where you had to watch 10ads per day which was made mandate else you could lose mined coins. After a while they released another update which made us watch 35ads for miners. And additional 35ads just to open the home page. In total 70ads. Now, every day even with proper offset goal reached the miner is reduced day by day at very significant amounts. Even after reaching support they inform its our issue with network and we didn't watch ads. Also, the app has been removed by Playstore for violating.
