Great posts for people learning. You are catching on fast! Once you learn the basics of bitcoin and Eth, you can go down the top 100 coins and figure out what makes them special. That’s how I learned. But the top 100 will change. I learned 100 coins and now only half of them are still up there, but I learned a whole lot and some of them come back from the dead if they have a good idea and a serious team developing. I think the serious team and community are what some of the others were missing, or they were aiming too high for a technology in its infancy.
