I would say that you should not look for trending ones, but strong ones. For example Bitcoin is still something that we can care about, and it is going to end up with a good result no matter what, if you trust that and believe that then you are going to make some good profit and some good money, not everyone can easily make that, but we are going to end up with it eventually, it just has to be done one way or another.

I believe that if you look at only the ones which are trending for the time being, like something that looks good only for now, then you are not going to end up with a good result, and you should avoid those. Because something that goes up just now, will not be great for the long term and you never know when it will crash.
