What is the problem with most of the projects is that they don't know they will need to work very hard in the first couple of years, and in that time to not take any profit!
All shady startups are like that. They have a lot of vaporware to tell people but are just going to exit the market after a few years. It is the risk that you have to take if you are going to invest in them.
Bounty alone is just a beginning, but every project needs upgrades, constant monitoring, developing on all fields, money they get to invest in equipment. Most of the teams take first profit and they abandon projects and investors stay with worthless tokens.
It is because the abandonment was a pre-determined thing. It cannot be proven but assumed because if project owners have the cheek to sell away the project and turn off all social media communication then there is no denying this fact unless proven otherwise. Bounty is a just a method to make some idiots promote their scam and get more investors, giving them some worthless tokens in return.
