That's true. But still, if I was a whale, I'd accumulate some low-cap coin with actual value instead, this should bring better profits.
Then what make you think that some low cap coin has actual value instead of sushi or others?
as I mentioned above, in cryptocurrency the value comes from speculation. even a project with a real working product sometime can not do much with those hyped token/coin.
cryptocurrency is full of manipulation and speculation, we can not determine which one will have an actual value and which one is not.
nobody knows what will happen in the future, just follow the trend and we will survive.
