Received Claude @AnthropicAI official email:

Refund MAX subscription before April 9th, and also get a $200 credit,
Wait, is arbitrage opportunity coming?
1. First claim the $200 credit (heard that some people can repeatedly claim due to a bug)
2. Use it up before April 9th
3. Before expiration, click to refund the subscription
Risk: Currently uncertain whether the credit can still be refunded after it is used up.
As expected, after doing trading for a long time,
I look for arbitrage opportunities in everything,
Everything can be arbitraged!🫡$ETH
