Lack of restraint and not setting the right goals is the problem many people are struggling with, impatience was my first lesson in investing. I filed a good coin and then when they haven't developed the platform. I try to sell them to reinvest. But the truth is that only 1 day later. That coin went up by 50% again. Lol, this is a prime example in many situations here.
seems obvious, but what time did you give them to develop a platform?
platform development could take months/years, and if the team is open and sharing their progress/ideas, I do not see a problem to wait a bit for a platform to be developed
do not give it on hype, hype projects are usually not good investment if the hype already started, although there are some exclusions there as well, where hype is enough for a project to rise
it is good to have a plan before investing money
