Hello Haejin.
At first, thanks for your effort in the steemit Community.
I highly appreciate that there are people who want to help other people, without beeing greedy and in hope that you profit from other guys.

On the other hand, i really want to learn your technique.
In my entire life i was fascinated on numbers.
Bad thing is, you can't live that passion out in general companies, since all want to make you a slave.

If there is any way to hold contact i would be very happy if you text me one xantoswow@gmx.at

Now im going on youtube again, see you guys and wish you nice profits !!

PS: Merry Christmas and happy new year
