My thrust in Ethereum is gone. The fact that the price rose so much after the banks got on board combined with the fact that they will go to POS makes me suspicious. What if they already own more than 50 %? Then they can manage ETH after the change, the inflation e.g. After this crash they could buy up even more, maybe they made up this rumor about Vitalic.
What if the banking consortium who were investigating how to use blockchain also were investigating how to destroy Bitcoin. It could be that they didn't find a way. Maybe the only option they found was to take over and hype the 2nd cryptocurrency that is far less secure and decentralized and let it overtake Bitcoin and call it the new Bitcoin?
But there are many more reasons that I don't believe in ETH at the moment. Happily I sold halve of my stack 2 days ago and wrote here why:
