How can I learn what's the next hot thing is?

[nathanN2017]

Is there a topic area on this forum where people share their beliefs about what the next thing that will increase in value to buy is?

My goal is to buy something, wait till it goes up 25% for example and then sell.  I assume a few of you do this already?

Any advice how I can turn this into full time thing to do, buy daily something, and sell that same day or next day, pocked profit and do it again with something else?

Thanks:)
