As you know , if you are trading at Dex you could easily see x100 pumps . After that pump, price down to usual point. So what is that meaning? If any whale wants to collect the tokens, there are many better ways to collect them more cheaper. Any clue ? is that money laundring?
It will be nice to see an example of what you are talking about since depending on the information that growth can mean many different things, in the past I have seen coins going up in value as much as you are stating but when you saw the volume of the coin you could see no one was buying and selling the coin, so it was most likely an attempt to lure investors to buy the coin and create FOMO so they could sell their coins for those inflated prices.
