It is not a good suggestion to follow and rely on the others because without learning it is impossible for the people to understand where to trade and where to invest, there are different exchanges and has different volumes. So you need to research a lot of coins which has huge potential in the market and has active developments will have the chance to increase their prices.
I agree totally with what you said, but there should still be a room for listening to people’s suggestion and opinion because we have so many experienced people in that particular field were we lack knowledge of, what I don’t support is working on that opinion without making further research on them.
If we are to take every projects we have in the market which you quite admit that they are lots of them, it will be impossible to get the right one on time, and the first 100 you might pick may be a wrong coin, but with people’s suggestion, you can get clue to the ones that are worthy of dedicating time to for research, otherwise, you will end up wasting a while year researching without making any investment. SO better we still listen to what people say but act on them with wisdom.
