The altcoins market is unstable actually, and recently ETH price decreased to around 150$, and that's, of course, affecting the new ICO and IEO projects. This market's situation isn't encouraging the investors to take the risk of investing in ICOs, and most of them prefer to hold their coins.
ETH price decrease will affect many other projects, at this time people are not very interested in investing and will only make you more frustrated. Currently, people are only encouraged to invest in the old coins available in this market to make profit because these are coins with stable markets and high liquidity, which will greatly reduce the risks.
This year I have very little investment in new projects but will consider participating in some IEO projects at big exchanges like Okex because this is often the place where many projects are profitable for investors.
