No it is not. You didn't pay sneakers with numbers, but with shares in ownership of bank's debt. Watch the video linked in OP. Numbers are just info on the quantity of shares. It's like 100 TSLA. 100 is info on quantity of shares in Tesla company. Debt in the banking system is the thing that exists. Tesla is the thing that exists. Bitcoin is a thing that doesn't exist. Numbers attached to the addresses are fake. People are lied to that they are buying bitcoin. They are not. The system just attaches numbers to their addresses.
You created a video for this nonsense? Oh my God, you are even more crazier than I thought.
OK, I agree that there is nothing physical behind Bitcoin like there is with traditional commodities. But you are looking at Bitcoin in the wrong way. Bitcoin is not a representation of something physical. It is Bitcoin. Just like an ounce of gold is an ounce of gold, one Bitcoin is one Bitcoin. There is nothing behind an ounce of gold because it's just an once of gold. It's the same with Bitcoin.
And Bitcoin is not just a number in a database. Go ahead and try to put a number into a Bitcoin's public ledger. If you manage to do that, I will buy that number from you.
Os course bitcoin is not a number. A number is a concept about quantity of things represented with math symbols (0-9). Bitcoin is a non-existent thing. People talk about it, write about it, think about it, blockchain has data on its quantity, but nobody is able to show it. That's what I am telling you. Bitcoin is neither tangible nor intangible. Neither physical nor abstract. Bitcoin simply doesn't exist.
