i would say in my opinion the best way is to research about the project , check the activities of the team and be sure they are developing the project constantly and following their timeline.
Like me , I saw #Bluzelle, joined their social media and bought some $BLZ recently after carrying out due research and seeing the huge potential of the project. Right now it has become the best decision i have made this year.
so make sure you follow any project you wish to invest in for a while in their social media platforms and ask some technical questions the way they respond may also determine the quality of the project and team behind it.
