I do not do this, but i am pretty sure there are poeple who do it. This is somewhat similar to copy trading, were people just replicate the trades of another trader, a more experienced trader though. The reason i won't do any of this is that i cannot just buy something because someone else it, does not matter if he is a Whale or an experienced trader.

I like to do my own research and i like my success to depend on me and my research, than on someone else.
