Have you ever heard of crypto-currencies? I believe that Bitcoin is far superior to any other crypto-currency. It is the digital gold!
I have heard of Bitcoin but personally I'm not a fan because its not backed by something tangible like gold or silver.
You have an argument there, but what is backing the value of the US dollar? The US government can print an unlimited amount of US dollars, causing massive inflation. At least bitcoin has a limited number that can be mined. 
You're correct. Nothing right now is backing the US dollar and I know that people can make payments with bitcoins.
Have you ever considered buying bitcoin? Do you know how to purchase it?
No I haven't because its not backed by something tangible and I heard that the transaction fees are horrible. Coinbase is the place to buy Bitcoin
As it becomes more mainstream, transactions costs are expected to decrease. As the world becomes more virtual, hopefully there will be increases uses of bitcoin for digital purchases. Have you ever had to get a computer repaired?
Bitcoins are tricky because if people can't hold it in their hands they won't purchase it. I know how to make my own computer repairs.
As the world becomes more digital, there are many assets that we no longer touch. This digitalization of assets will only increase in the upcoming years. We will likely not even anticipate some of the digital fads coming. An example of this are NFTs, have you heard of NFT art?
They are Non Fungible Tokens that usually egamers use.
