ICOs are collecting funds in multiple currencies and on that way they can get more funds. It is a good thing as investors are holders of different currencies. It is only and administrative thing and has not much with the success of the project.
Actually even if they accept only one currency as long as they are legit and good project, they will still raise a good amount of money.
I've seen in the past that only accept ETH as an investment but project was sold out.
Maybe this time they are desperate to raise that's why they give more options, the market has no fully change and IEO is the new trend now.
