guys if you buy at youbit - you buy NOTHING. there's no guarantee you will ever be able to withdraw the coins from there.
You dont know what you speak of.
YOBIT is a strong healthy exchange, with volume that has been significantly increasing month by month. I have never had any issue with them what so ever.
They take advantage of selling IOU's because they invested a Large amount of btc's into the project. I have huge faith in yobit and know they will come through and deliver to the IOU holders.
On top of it. The pump, and price on yobit only helps ICO buyers because it gains attention to the waves project, and gives confidence to ico'rs that thought they would loose btcs upon launch but now will probably start posting Lambo pics.
