This is not the first time I am coming across this post in this forum although it seems to have been discussed in the bitcoin discussion section with more graphic and explanation, i could had commented here but was actually searching for the post i can't really recall the title of that topic or thread. But however, let me delve into the topic of discussion..

As you know Shrimps are like newbie investors they jump from wall to wall or from one side of the market to another with no or little panic in that water (market), immediately such happens they don't mind dumping seriously to save their heads because they are afraid of being caught in mid way.

Then the Fish as you may have explained it are people who has passed a little bit becoming a newbie, like they had more fate and believe that no market condition would make them drank so easily and they must survive any amount of water current and waves that seems to pull them out from their usual operation.

Dolphin as the implies shows that these sets of people are actually more relaxed than those who are classified as fishes but they are colorful in what they are doing, therefore they don't easily comes out from the water no matter any wave or water current that may seems to have stirred up the water instead they would just bring out their heads and breath then sink back again or possible they felt like they needs fresh air then dip down again. Meaning this people don't easily sell off their holding except they had a pressing need that either requires an urgent attention to be solved.

Now, the Whales to me this people are also called the trouble maker why? To me they naturally comes out of water to scare people away(traders) while coming, and if you aren't that mindful or careful you could get sunk into the ocean or sea, but most importantly provided you have self trusted and having a nice ship ( trading experience) to sail on then you won't sink so easily they just panic for no reason and if you don't careful control yourself you got drown by putting that fear in you. This means that when you are holding bitcoin and you witness any huge dump you don't have to immediately rush to dump your coin instead those dump are being created by the whales to have their bags filled from little investors and traders, and immediately it's filled you would see that the market would stabilized again by then you had end up selling your long holding bitcoin in your possessions.

The important keys is that you must always understand how the market works to avoid being cut off from the routs where you should be, and you must defined your investment plans and where you should be. One can't be a Shrimps and expect to acts as Whales, at least it's gradual and then you could turned to whales but you can't compered yourself to the other without you having to get that level of investment.
