yes of course now is a very appropriate time for investment in ICO because I see the cryptocurrency price is currently falling very deep and you should be able to use this still cheap price to enter and invest in some ICO that you think is safe and suitable for investment .
Other reason for investing in ICOs right now is that in the current market the price of all the coins are lower and the whole market is down so the projects have kept very soft rules for investment and they need investment while in the coming year when the market will be up people will invest on a large scale and it is expected that the rules will be more stronger.
