I am very happy that your sharing is useful.
But if you explain to a person who always treats Bitcoin as a scam that Bitcoin is not a scam, you will find that no matter how you explain it, they will follow their ideas. Your explanation is useless. I once talked with a friend for half an hour, and he remained indifferent, just believing that Bitcoin is a scam. I can't do anything about it. He doesn't believe me to let him watch me operate the transaction.
