I think you are wrong, cause bitcoin is so usefull for everyone. Can you see many people are now so rich and successfull because of the bitcoin. And if you say that transaction nowadays are so long before you get your money, that is just okay for those people who are willing to wait to get their money even it costs a week of waiting before you get your money.
Of course he is wrong - bitcoin was buried for so many times these past 5 years. This guy is nothing but a con man. His reasoning not making any sense
