The key to this is to not trust the promise of any project
Instead trust your focus on the project; do u see it as a short term or long term project ?
Do not be impressed by a project; get motivation from the profit you would derive from the project
I know that the reason why we are all putting money into some of these projects is for us to make profit from them, but for any investment we want to put money into, we still have to pick interest in the real use of the project first because that is the only thing that would guarantee if the project will have a future or not.
Let me tell you, everything is not about money, those who invested in the technology that majority of us are enjoying till date, if they had only focused on the profit on it, do you think they would have succeeded in raising money to build any technology that we are using now? The essence of what I am just trying to say is that we need to always be very patient, and watch the growth of a good thing that we believe in.
