there is a problem in real word how to use your bitcoin as a collateral to take a loan and legally avoid to pay taxes for.e. You would have basically 3 solution in the future: 1) use a third party by BTC ETF (backed by the word of banksters, true BTC maximalist never) 2) use a lawyer to conduct a contract (even poorer risk management) 3) tokenise it on smart contract platform. What would you choose If you would be owner of a big company trying to save your purchasing power in BTC value?
