My suggestions to not to buy the account he is selling because As of the latest update of btctalk you are not able to recover your activty points of gone years , days ,months so better keep your money

Isn't maths really easy when you understand?
Do you realize that you dont need to do math when you can pay someone else to do the math ?
But what if the math tells him that he would profit more by using the result himself?
how come math would tell him that way ? isnt it true that larger scale means more profitable and larger scale means you hire lot of ppl to do the math instead of doing it all yourself ?
