And are the risks higher!??
The risks are higher that is what I believe this year. If bitcoin would have been growing the same way as it did last year then there was great chance for the altcoins to grow along with the coins which are coming out of new ICO project. The reason is straight, if bitcoin stays healthy then it is far greater for the altcoin market to stay healthy because it is actually support for the projects when they raise huge amount of money for their development. Its simple fact that if bitcoin drops in value then ICO projects are incurred with huge loss as they carry lower money as compared to what they raised initially. I think this point is enough to explain why most of the ICO's will fail this year as they will have less budgets virtually.
