A juicy one!

To break it down:

* 1kx, an investment institution, sold approximately 313,737 RPL tokens (worth around $371 million) to Amber Group over the past 12 days.
* This sale represents a significant portion of their total RPL holdings, which were acquired through an investment in Rocket Pool in December 2021.
* At that time, they received 570,393 RPL tokens, which they then fully staked on Rocket Pool nodes. Currently, they still have around 315,835 RPL tokens (worth approximately $363 million) staked.
* The recent sale was likely motivated by the price increase of RPL after Coinbase announced the listing of RPL contracts. The token's price surged by 28% following this announcement.

Overall, this news highlights the significant scale of 1kx's RPL holdings and their willingness to monetize them when the market is favorable.
