With respect to ico, you explain it very comprehensively. However, at present, most countries are not friendly to ico, because ico serves many frauds, and there is no specific policy to supervise ico
But I think for ICO is an initial coin offering that offers to give other ways of making money, ICO is a form of different levels of type and quality, is also a tool with money. However, not entirely all types of ICO have a good price level, there are some ICO that someone say pesky coins because of very cheap value.
