what about this strategy?
sell Lisk holding, buy Waves, sell it 3x on launch, buy Lisk back cheap?
Waves wont be 3x ICO price on launch

it is overbought already by people who want to dump on launch, just like you. Waves is only longterm now, because of ICO hysteria, amount of funds is speculative not based on fundamentals and honest interest in project. Also no time window between ICO and exchange = DAO scenario.
No time to create new demand for coin.
earlier today sasha confirmed that Waves will not launch until at least one week after the ICO closes. that was news to me when i read it. i had thought it was close and then trade immediately (like DAO), but no.
