ICO is too risky right now..investments to Bitcoin dont gives much profit and the price of bitcoin is also much valuative.. what about mining? is it still stable income?
Risk is not the only issue which can be there but we will have to brave enough for investing even then, mining has been good way of making money but it takes a little more money than investing takes, because for this you will have to pay electricity bills which will be consume by mining equipments, otherwise mining is also profitable.
