Ethereum's upcoming upgrade, Shanghai, is said to happen on March 2023.

This hardfork will enable ETH staker and validator to withdraw from Beacon Chain which said to be approximately 16 million coins or over $25 billion.

I wonder how this will affect Ethereum ecosystem and the "universe" of cryptocurrency.

If those staker, who for many years waited to withdraw their rewards,  will eventually decided to "dump" this will cause a huge effect to the market though we also know that they have many faithful and loyal supporter who thinks and believe the greatness and usefulness of this project.

Ethereum is still the 2nd most dominating cryptocurrency after bitcoin and I'm hoping Buterin have a great plan to convince those holder to keep their rewards and not to dump it.
