thank you sir for the answer, with like this I already understand what is satoshi school.
sorry if my question is not connected or I have disturbed the father with my question sir, I asked the father because I do not understand sir.
I think you do not want to reply to my message or my questions sir, it turns out sir is a good and caring person to us who are studying and working on steemit.
once again thank you sir @skorek..
