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? 
You aren't alone here, everything aren't knowledge about some thing will be waste your time to continue. Alot of people here such as newbie and higher rank are have same problem with you. about scam project and shitcoin are you followed.
don't worry, you have a time to learning here, we are newbie here.
