I believe there is no more payout after the first 4-week payout. Meaning a post can not make any more revenue past that.
So my point is it is possible to recoup the cost and maybe profit but looking at it as a longer-term investment. There might be a big audience for some languages today but in the future there might be. It is somewhat of a gamble looking at it this way.
But for that to work dan needs to extend payouts past the first 4-week payout.
Unless this was changed in the last hard fork?
