I think with the increase in BTC, of course this will affect the prices of some altcoins in the market, but it seems that it will not affect investors' interest to invest in ICO, because we know for sure with the increase in the price of bitcoin, investors will invest more in bitcoin or altcoin which indeed already have an exchange market instead of having to invest in ico which does have a fairly high risk of fraud.
About ico, no one is talking, since this topic has already died, bitcoin in the future will clearly increase its value , but at the expense of altcoins it is difficult to predict, due to the fact that many altcoins die.
