For some reason since 48h im getting BTCs showing up in my wallet with status "mined". Its not full blocks like 25-50 BTCs but some random numbers between 0,1-1BTC not regurarly.
What is that? The coin are fully verified and working but how the hell am i getting them?
Even though my miners are not that powerfull I do the same from time to time. Mainly to thank people or encurage certain projects. Just change the payout address with the pool or cloudmining service and forget about it for a week or two.
A typo is so unlikely that you can consider it impossible and since it happened more than once its most likely no misstake either. Just to be on the safe side Id keep them for at least a week. Maybe someone will write you.
Now that I wrote that, make sure its not a scammer first
