Dollar cost averaging is built right in to this ICO! LOL .. so it doesn't much matter if you buy now or later, as long as you buy all the in-between as well. ;-)
But seriously, have to say No, because there will definitely be more opportunities to buy in cheaper, and it is best to put all your money in on a single day, than spread it over time. KEEP AN EYE OPEN FOR THAT DAY!
