Of course it is use to raise funds , for me I am investing to existing company that are adopting blockchain company because it is more safer doing this , because most of the ICO Project nowadays are scams which is bad for new investors ! If you are looking for decent ICO i prefer WPP Energy that is established in Switzerland , the company is one of the leading renewable energy provider worldwide , they are also adopting blockchain technology to operate more efficient and also to incentivize the use of clean energy !
