fast math is 3 x 700 = 2100 retail price
his math is 3 x 400= 1200 + 700 = 1900
so you save 200 bucks
if you knew you wanted 10 cards
10 x 700 = 7000
10 x 400 = 4000 + 700 = 4700 this would be pretty good if it was real.
but if you really can get cards at 400 why no get 20 x 400 = 8000
and then sell at 550 = 11000
so I ask you op why not get 20 yourself
That would be the best option, unfortunately I do not have the funds to buy said amount.
So I thought id sell the method instead.
But you have a point, I might be better of selling the batch I got so far and reusing to buy more ~ might make more than mining itself lol
