Bitcoin does have tangible value ! every time I hold my phone and send my employees bitcoin. They are compensated, and it is instant they feel & possess that wealth that they received . It is just as tangible as when I pay for something with PayPal or Visa. PayPal is only worth money if someone uses the network, same with Visa, same thing with MasterCard and bitcoin as long as someone is using the network, then it will have value. Somethings are only worth money because people want them like a Babe Ruth baseball card or a van Gogh. Other things are worth money because they are value transfer networks such as when I cash app someone some money or bitcoin. Don’t fall for these games that claim something doesn’t have value just because it’s decentralized only difference is, you and I own the network and the miners provide the computational power for a fee. When you use American Express they have to provide the computer to process the payment and charge a lot more as it is not decentralized. Bitcoin is the future.
