There is a lot of excitement these days about ICOs, and with the big run up in Etherum prices this year, lots of people are flush and are looking for the next big thing to invest in. http://cryptohustle.com/are-the-crypto-markets-in-an-ico-bubble With all of this money going into ICOs, people are expecting a big return and are waiting to sell when the price rises. With this long ICO period, some people will want to sell their waves on the first day of trading, and if the price starts to sink, investors are going to sell. It could be snowball effect out the gate. That doesn't necessarily predict the long term price of waves, but I've seen lots of coins sell hard on the first day of trading. Waves has an ICO lasting 6 weeks. That means lots of speculators have plenty of time to get in. The more people are involved in waves ICO speculation, the more likely someone is going to sell as soon as they can, and that could lead to cascade of falling prices.
I'm not saying it's going to happen. I think a lot will depend on BTC prices and the health of alt coin markets on the day that waves start trading. But definitely with this looooong ICO there is a risk of price plummet.
I would be happy to buy more waves at a lower price.
I'm in for the medium/long period
