In my opinion whale signals are never the real thing. They might exist but normal people will never be invited. So 99.9999% of those trading signals are just scams to get you to pay a fee.
Anyone offering predictions should be ignored. I have been trading for years now and never once have I heard or seen a real whale group, selling signals to small investors. What I have seen are pump and dump coins looking for victims.
Do future yourself a favor and stay away.
Reality is that "whale movements" are a real thing, but signals of it is not. I mean just because a whale moved their money doesn't mean that something will happen, unfortunately not a lot of people realize this. I think it's quite important to remember that if you are doing something because whales are doing it, you are not 100% sure if whales are actually doing it.
You could see 50 million dollars withdraw from the exchanges into wallet, or could see wallet going into exchange, doesn't mean anything is actually happening, may look like something will happen but doesn't mean it will. This is why it's quite important to not take them as signals. Yes whales do money around, that's their thing, they always do, but that doesn't mean it's a signal for you to buy or sell.
