Alot of people are waiting for the 1$ mark, and some higher prices. So most people would have been caught by the flash dip. Taking profit is a personal decision such as the consequences also.
There is nothing wrong with people waiting for the $ 1 mark on a good token, because that is the expectation of a large number of token holders, even though some of them were able to make good and clear profits in the past few days.
This time the people who have been selling their XRP at 70 cents were able to buy back again at the bottom price due to the bitcoin dump.
The flash pump of XRP was happening when there are whales who have been trying to load so many XRP coins on their wallets.
The instant buy will create a big pump and then it will be dumped again as the whales itself will try to take some profit from there.
