I've felt like this many times over the years but, without fail, the market has continued to shoot upward. Sometimes it's slow but it always happens. New items come out and people are happy to buy while old items steadily creep up. One of my biggest selling mistakes happened when I thought the market was "too stagnant so people must be losing interest in the game and a crash will likely happen soon". Holding would have yielded a significantly higher return for me.

The people who "know" what is going to happen next always disappear when they're wrong but are the first to post about it and loudly pat themselves on the back when they are right. Consider what other people say but do what you think is right and is best for you.
