I began to think this would be a waste of time with everything I learned because almost all the projects I had followed ended in scammers. Is this a waste of time for me?

How many coins or campaign have you participated in, and all of them comes from ICO? participating in bounty and investing in a new coin or even a coin in the market is not a walk in the park, you have to make due diligence, even old timers are making mistakes participating in a project that turns out to be dubious if are having a second thought on a project, don't invest yet and ask old timers but in the end it's you who should decide.
