It's not going to die because you say so. I'm yet to see at least one sign of it dying. A 10% drop in value on a tradable asset is not a sign of dying.
I agree with you. He seemed frustrated regarding the Bitcoin price, so maybe he is losing profits right now? Nonetheless, Bitcoin has been presumed to be dead long before. But it hasnt and it wont, because many are still into it and believe on it. Bitcoin is not at fault for the existence of scammers here, scammers will always do their ventures whenever and wherever possible.
Just look how we've evolved in the last 5 years. Not long ago people were frustrated because Bitcoin was below 5000 USD and now they complain about going from 11 to 10 thousand.
Hopw can anyone be frustrated about 10 thousand dollar Bitcoin is beyond my understanding.
