Welcome to the year 2018 where the real ICO are getting launched. They are ridiculously high, yes but they know how they working behind the project and how to make it successful. Yes, we still need to checkout which is the right project and could be another hit in the future. Not every project reaches the milestone in the specified timeline and then people get out of it early and make the project look like worse. This destroys the marketing funds, project development funs in the long run and hence now a days ICO plan to catch up more funds from the early investors. Thats why they play in the stakes and limit the minimum amount of ICO price to more costlier package. Seen that many times and may be thats why you thinking the ICO rates are increasing higher.
