After some quick searching the amount even medium size sites like this can make is something to look forward to. The POS is like what 5% - 10%? So 10% of 85BTC annually needs to be brought back.

8.5btc buy backs per year to cancel POS 'dilution' needless to say that is close to nothing and also nothing to be even the slightest bit concerned about when taking into account....

A, The potential earnings of said site.

B, The above is not taking into account, coins will be burned as well as buy backs which makes the POS even less of a concern not that is was anyway.

C, This is going to the moon if they complete their milestones.
