Participation in ICO or investment at pre-ICO stage is a very risky step. Its just like purchasing a shop on 40th floor and the ground floor of that shopping mall is just start to build.
There are so many ideas/concepts is trying to prevail in the market but is there any formula to separate strong project from scams/weak projects.
Which scale should an investor use to go before investing in a coin? Is it the code, or the system it based, or their community strength, or is it depends on their venture capital that how much big it is?
In my own point of view, the thing you should consider before investing in a coin take a look first on its details and see if it can be trusted because there are now a lot of scams. And better check if is worth it to invest with because you might don't get a huge profit from it.
