This doesn't mean anything at all. Some big whale with 1000 btc can create 1000 individual wallets with 1 btc in each. What information would you get from this? Nothing. Even if these were all legit people holding 1 btc, that wouldn't tell you anything too.
Some exchanges/casinos also hold their coins like this. They don't hold all of their stash in one address so it won't gather attention.
Probably a hype that many people want to. This simply wants to emphasize that there are more investors engaging to Bitcoin or this industry in general, with huge amounts. But problem is; somehow it does not reflect to market behavior at the present. If this one is true (like if there are really whales entering again in this industry), prices should be having huge increase because those are whales we are talking about who can make a 'wave' with regards to cryptos' market value. But I do hope that time will once again come; where whales are moving around which before created a huge pump with this market covering multiple tokens. But for now, reminiscing of the good days is the only thing we could do in order to endure the market behavior at the present.
