the problem we have right now is exchanges cost btc to get listed . if we sold priv to pay the listing it would dump the price right down. we can't sell priv at these prices as we would have to sell too much
That's a problem projects that distribute their coins via airdrop have to deal with.
There are so many pros with this distribution but this is the only con I can come with.
But when the volume will be higher and the market will come up, it will be easier to get some funding by selling some PRiVs.
