Bounty pools can not be used to manipulate price and should not be used like this. However, I believe that other projects sufferred same tough period as well due to the rises of bitcoin. People all try to sell their altcoins, then buy bitcoin and hold it to enjoy bitcoin increases. Therefore, most of altcoins have fallen down around 30 percent to 50 percent during last two or three weeks. I don't think there are serious things with VEIL and its promotions. The coin has suffered from bitcoin latest movements.
Hmm.. during the last 7 days, the exchange rate (versus Bitcoin) has fallen by as much as 50%. Today also, Veil fell by another 17%. This is unlike the case with the established altcoins, most of which are going up. One of the top-5 alts, Ripple has gone up by 20% during the past 24 hours.
One thing I have noticed is that today the volumes are down. So the only explanation for the recent price movement is that the supply remained the same, while the demand showed a decline.
Every time the market can't be the same and even with the coin price, we have to buy them according to the situation of the market. Not only the Veil look at the other potential coin has decreased their value if you compare with their previous prices.
