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?
So basically you are considering those coins that will be put on ICO? To answer the question directly, it will depend on how far your analyzation about the said project will goes.Almost all projects have a good roadmap and future plans but the question here is, are those plans will be really implemented and follow in the future? At most of the cases, if ICO didn't reached their expected target of funding, the development will soon stop. And sometimes, even some of the projects reached their target and able to build a good community, still their plans takes times to execute and the worst, developments will just stopped without a trace. That's how risky participating in an ICO.
So what to do now? My suggestion is to disregard investing on those coins via ICO but to consider putting time to learn how to choose a good altcoins that already in the market and can ride the current market behaviour. Will not mentioned any of those altcoins since we might have different handling them.
That will be your homework for now. Well then at the end of the day, you are the only one who can think of a way how to deal with your concern.
