Crypto watchers are setting their sights on Etherum this week, as the currency undergoes an upgrade that some think could have a negative impact on the price of the coin, at least in the short term.

The ability to unstake ETH and their associated staking rewards earned so far has some investors worried, as it could enable many users who were previously unable to sell their staked ETH to dump their
