The developers of Etherium plan to activate the Merge fork on September 15, as a result of which the network will switch to the PoS (Proof of Stake) consensus.
In anticipation of this important event, miners are accumulating ether.
According to OkLink, more than 261,000 ETH totaling up to $415 million have accumulated on mining pool addresses. The last time a similar situation was observed was in April 2018, the researchers stressed.
