FACT: The coin price of largest ICOs has dropped by 60% on average upon launch on exchanges.
Conclusion: Skip buying WAVES ICO and buy cheap WAVES after it launches on exchanges in next 2 to 3 weeks
I've looked at the first chart(Etherium) and this is what I've found.
At the given time frame ETH price range was from 0.01 BTC to 0.0024 BTC .
BTC price range at that very time was :278$ to 263$
So, 0.0024x263=0.63$
And ETH ICO price was 0.30$
In other words Etherium price was never lower then its ICO price.
I didn't check other coins charts provided though but there is a reason to think they are going to be incorrect too.
PS. Lowes ETH went was on October 21/2015 and it was 0.41$
