If the encryption is broken Bitcoin is the least of our worries, everything is then broken including all financial institutions as they all use encryption. There would have e to be a quantum proof encryption method that may happen by the time any quantum machine could actually do break our current encryptions.
So your perspective is to not worry about it because other institutions would have issues too? So would you consider yourself very risk tolerant in this case? What would be key indicators for your risk evaluation to increase?
