what ico can affect the market price? and what ico is more risk in comparison with trading as usual
Well probably the ICOs that have forked to a more reliable and relevant Coin like Ethereum or something. I mean it could help a lot for that coin's market price, it will also affect other coins.
I think the only risk in this is that those ICOs that have not raised its budget to its expected amount to be collected for the project and that will gradually result a decrease to that coin price in the marketplace.
