In some news, it is written that the whales of a coin or token have tried to sell or buy that coin or token, and in this way they recognize the time to buy or sell that coin or token. How can I see the transactions?
If you want to buy a coin solely because a whale moved some of that coin, then maybe you should rethink what you want to do. For starters you don't know if the whale is just moving their coin from one of their wallet to another or if they are actually selling it. That being said, alerts of whales moving their coins can create FUD, but only for a short time, thus if you buy a shitcoin because of such alert, there is a high chance you'll end up bagholding the coin.
Buy a coin that has an actual utility, like Bitcoin. Don't buy a coin because a whale bought that coin or because of hype, because all of that can only last for a short time, but a coin with an actual utility is sustainable for the long term.
