Bitcoin is the digital currency of the new generation and it is more created for entertainment. I do not expect a long-term outlook, because without the Internet, it will simply disappear.
I don't think it's more created for entertainment but it is certainly created for avoiding centralized transactions and it is good for investing. Why people are keep on telling about the disappearance of internet. With the current situation of the world today, internet is a necessity and it is not going to disappear, so bitcoin will remain and will be treated as money and investment.
