Bitcoin price has influenced the market overall. With increase in BTC price, people will invest more in other projects, but not sure if in ICO itself considering the recent status of it in the market.
I don't think people will invest more in other projects, my guess is the opposite, people will constantly invest more money and transfer money from other projects to bitcoin because this sudden increase will create a severe decline for the market when pumps from bitcoin are based on money from other projects, a common trend that I see from people. Therefore, in this unexpected situation, if we have the opportunity to escape, we should escape, should not hold on to other projects, less loss will be better than a state of suffering in the long term
