Why does vezt price keep dropping since ico? No rebound whatsoever

Its partially because the market is down. Its 530B compared to 840B in early january. But the main reason is because it is so little news from Vezt. We get very few updates on whats going on. In cryptomarket especially people sell the second it goes quiet. It goes down on average about 10% each day, which is much. When I bought at 60 cent i thought it wouldnt go down so fast.
I bought first at 60 cent, then I bought more at 40 cent. If the price falls to 30 cent I buy probably even more. Now the price is below ICO price accually. But I think its just a question of time when it will rise. Maybe 3 days, 2 weeks or 1 month.
One thing to notice is that most tokens are sold in presale. They have a 3 or 6 month lock on the tokens Vezt told us. Half is locked 3 month and half until 6 month. Which date this is from, I dont know but I dont thing anyone got their tokens before january?
