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 is, 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.
How do you do your own research then? Don't your spy on what more experienced traders are buying at a time and the amount they put in which sometimes tells their level of confidence in the project, I guess.
However, I would like to do how you start your own independent research.
