A friend of mine has recently gone crazy.

Every day at home, he bangs his head against the wall, shouting, "I am just an idiot! I am just an idiot!"

His wife was frightened, thinking he was possessed, and quickly called a master. The master calculated and said, "There's no need to panic, he is not possessed."

The wife asked, "Is there still hope?" The master shook his head, saying, "Being possessed can still be saved, but trading coins... his life is considered ruined." $btc
