Facing out of ICO will not be likely as some will still prefer to donico than IEO as a new measure to safe investors .
Well the real investors will prefer ieo than ICO as at the moment for safe reason cos manynico will run away with investors funds while ieo are save with the exchange and can be return if the main soft is not achieve or the project has issue easily to retain the reputation of the exchange.
It seems to me that everything depends not only on the reputation of the cryptocurrency exchange, which holds IEO, but also on the capabilities of the developers of new projects themselves. The fact is that not all teams will be able to fulfill the conditions set by those exchanges that conduct IEO. Based on this, the company's ico market will still exist and act.
