I don't get your point here. Indeed, the investment capital of a normal trader cannot be equal to the trading capital of a whale, but if a normal trader makes a trade with a whale, on the same cryptocurrency but with a different capital, both would lose the same percentage from their investment if that cryptocurrency loses value. So if you invest $10k and lose $6k in that dip, the whale would lose $600k if he had invested $1m. So the loss percentage is the same and it's based on a trader's loss appetite.
Regardless, a normal trader can't know a whale's movements and when and in which cryptocurrency they will make their trades in, they tend to manipulate the market so that they can earn profit from small traders, so they would never reveal their secrets for the general public.
