The crypto market exists both positively and negatively. Positive when the coins are coming to life with new technology applications that change our lives. But on the other hand, work out so many coins has the purpose of development as well as application technology. This mainly runs for its own profit purposes and makes the coins worthless in long-term investments.
I've seen projects that really has good technology and good project timeline but it still don't succeed since there is no enough community backing it up. The most important thing to consider for a coin is how much support it is getting regardless of how much good the technology is. I will prefer the simple project that has good community than a high technology project that has no enough support from people. This is why, it is always best to choose a project that is already well established since the community keeps growing already.
