I also invested in many successful projects in 2017, but unfortunately I didnt take profits, now the cost of coins is very low, I think that the factor of a successful ICO is the state of the market.
That is not a successful project because a successful project is one that should be able to put smile on investors face and make them proud for being a part of the project, but right now, how many projects are actually making their investors happy, they are only successful because they are able to raise the fund needed and then go on an exchange to list, But what of the real use case of the project? Have they ever been successful in that aspect
Many of us attribute their success to the fact that they were listed on an exchange but that is not right, it is what they continue to do and how they continue to make the word see their quality service and product after listing that I call a success and only few project have been able to prove themselves right in that regards.
