i don't know why you said "whales say so", since whales are either silent and say nothing while accumulate without letting anyone know or they are the most noisy people around who try spreading FUD to force others to sell so that they can have access to cheaper prices for their accumulation.
in any case things are NOT good or bad because of what whales do. things are good because bitcoin is a solid decentralized currency which still has all of its features that made it good in first place.
Quite a few whales voice their opinions about Bitcoin and the speculate what the price will be in the future. A lot of celebrities which are invested in Bitcoin that is public knowledge will try and manipulate the market by either praising Bitcoin or rubbishing it. What you can almost guarantee from any whale when it comes to advise from them is that its likely market manipulation rather than them giving genuine thoughts about the situation.
Whales have a lot of money invested and are good at what they do for a reason. Anyone who holds a large amount of coins has the potential to affect the market by moving those coins. But they also have a lot of pulling power in the media as they control a large portion of coins and media outlets like the make a big deal whenever a famous celebrity or someone holding a large amount of coins does something minuscule such as splitting up their coins. Its almost always spinned into something negative about Bitcoin. "Oh this whale has split their coins in attempt to sell" or something stupid like that. When in fact what they are doing is being more secure by splitting their funds.
I would take anyone's advise with a pinch of salt when they are personally invested in Bitcoin and have the option of telling the media. If they are telling you one on one it might be a little difference as one person generally doesn't have the power the influence the market unless they are holding a large amount of coins. If you are holding a large amount of coins and another whale tells you what to do. Don't listen to them as its likely manipulation.
The point I'm trying to make is make your own decisions and stop relying on news and celebrities invested in Bitcoin. If you believe in Bitcoin then invest if you don't. Don't. Its really as simple as that.
