Hello this is kushagra Singh and I am going to share my experience with you.
I use this app when they set their withdrawal limit at 41250 blocks means 6000 satoshi.
At that time I will get money and give not much effort for money.
At this time this app become wrost because they increase their withdrawal limit upto 110725 which is also similar to 6000 satoshi because of this dont think there is any sense of wasting time on this app.
Some times the 500 blocks button are not work or some times it gives only add but not give 500 block. When I contact with support they told me to reinstall the app but problem is not fixed.
I think they should decrease the withdrawal limit other wise not only me many people starting to uninstall your app.
