For example, I see an alert like:
"🚨 500 BTC transferred from unknown wallet to Coinbase"
My interpretation of this, is that this whale is expecting the price to go up, so its moving a part of their BTC into an exchange to start trading leveraging that capital.
Your interpretation is wrong because for starters you have no way of knowing that it was a "whale" that transferred those coins to Coinbase. It may have been Coinbase itself that moved coins from one address to another address. Not to mention that most of the times what these shitty "alert" sites call "moved to Coinbase" is baseless claims, they just see a big transaction and that's all. It may not even be to an exchange, it may be from some random address to another random address.
They call it "whale" because they are desperate for followers.
But, the comments I read on the style "game over" or "time to move to ETH" suggest the opposite.
Those are FUDs and trolls and some shitcoin advertisers that are desperate since their shitcoin bags have been losing value for the past 4 years.
How do you guys read the Whale Alert tweets?
You shouldn't waste your time because it is worthless information as I explained above.
