OK honest question: what's a whale?
A whale representing big fish, or Cryptowhale means these people are holding a huge amount of crypto. when the market is down people say "whales selling on the market"
because there's a big effect on the price because they are holding a huge amount of coins.
This may be the ideal one to think. But sometimes, we don't know what will happen to us. not everyone is a holder or long-term investor. SO, we cannot be sure enough that we will not sell our BTC. Sometimes, we need money to cash out also r take profits. But yes, 1BTC=1BTC
That is why never invest money that will be needed for a short period of time.
