It's currently $286 on coinmarketcap. I need to buy some ETH to participate in an ICO soon. Is now a good time to buy or do you think it will go down more in the next few days?
Right now the price is lower than that so you can take the opportunity and buy Ethereum, since you want it to buy into icos I suppose that you do not want to hold for the long term, while it is obvious that you want to maximize the amount of Ethereum that you can to get for your bitcoin I think you should not look too deeply into this, you are just wasting your energy, only watch a coin if you are going to be in for the long term.
