Since so many ICOs seem to be getting done privately by big institutions investors where the public needs to have connections to get in to a large minimum investment (Eg. 100 ETH+)...
Do you think Public Pre-Sales (e.g. minimum 100 ETH) or Pre-Sale Pools will even exist in 2 years?
I think ICO will still continue to exist even after 2 years or 2020. There are lots of benefits that an ICO can provide both the devs behind it and the people investing in it. As we all know ICO or Initial Coin Offering is a great way to raise funds for developments of the new project that they are trying to promote or launch to the public. This is also one way of letting people be involve in their project to get their name out and be adopted to society easily.
In the investors part ICO is a very big help as well if you want to increase your money or get some profit from your investments through buying shares from the company doing the ICO. I know there are lots of scam ICOs but with the proper research and knowing the foundation or the big people backing up the project there's a better chance that you can profit if the ICO that you participated in will be successful.
Here's an article that will help you tell or detect if an ICO is a scam.
