Too many alt clones. Imagine the coming newcomers to crypto seeing all these different coins. Its confusing as hell.
Not all are clones, there are a few with code written from scratch with interesting features, and a few alts modified from bitcoin's code with changes improving on bitcoin's functionality, that bitcoin will most likely never adopt because of its size of a behemoth. Of course, 95%+ are dumb clones, and they are confusing.
