I don't buy that argument at all.
No volume means no buying interest, it means no one cares about the coin (owning it).
Markets don't change, right now there are no buyers, otherwise there would be volume which translates to a healthy trading market.
There will be interest once the media campaign starts... until then people don't want to sell.
Many people are holding a lot of these and you will see that by checking the top 100 rich list daily. No one is selling.
Only a handful are trying to sell piddly amounts at a low price.
People have been buying in on the bid for quite a while and they do not want to buy at the ask to push the price up.
I have personally been getting some private wealthy investors on board for the past few weeks.
Volume is low now because the sellers at the bid have dried up.
Markets are ever changing.
