I do not think tracking whales alone will be sufficient for anyone to trade cryptocurrencies profitably. Usually, trading needs lots of factors to be analysed but you are sounding like just tracking the wallets of whales alone enough for successful trading. You may be right for one or two instances and definitely not for every time.

In my opinion, whales movements are part of market manipulations. If you are gambling in the name of trading and trying to copy the manipulations of whales, you may succeed in one or two times out of 10+ attempts. This is how exactly gambling works and I do not think that's how trading should be done for consistent profit making.
