If i would have more money to spread at this moment, i think that i will think it twice, probably i would put some funds in ethereum and the rest on another ICO, we are on a bear market so it could be a good decision
Investment in Ethereum is a good decision as the price is down but I don't think ICO is a good option to invest you funds because it is very risky now a days to invest in an ICO. It is also very difficult to pick a potential ICO. So I suggest you not to invest in ICO chose some other alts like XRP etc. for investment.
If you invest in Ethereum, you will not make any mistake. This altcoin will be only growing with time. Naturally, it will not run to the Moon as fast as you expect but it will happen, I am sure of it.
