I would be interested to know what you think is the biggest criticism of Bitcoin or where you see the biggest weakness?
And what would you respond to this criticism if you were confronted with it in a conversation?
For me, the most important to respond to this in conversion is to always acknowledge it, acknowledge the issue or concern, and not invalidate it.
Next is don't focus on the issue or negativity, showcase or highlight also the positive highlights of Bitcoin, like mentioning some positive things about Bitcoin.
