The market conditions are weak, but if the project is good it's better to start now because it will take 1-2 years to polish it (including ICO, developing, testing, and working beta launch). So if you want to take your market share then don't wait, start it as soon as possible.
Well yes for the meantime as this year icos are doing it for long term to see its development and in return the price can't be seen to stabilize. Though we can see icos that controlling the price not to get dump yet it's hard to fully control it as many have is short temper about their profit. Nonetheless, if you want to see an easy profit then stay away from icos and just invest in some coins in CMC.
