Yes please let me know when somebody actually spots that Japanese guy…chuckle.
At 7 transactions per second and global electricity needs already as large as some countries, bitcon will never be a currency.
Then, if they close the exchanges in your country, some in the basement of hackers homes, you got a problem. You will never be allowed to spend it.
Somebody, somewhere along the line, will steal it.
A lot of criminals involved.
