If transaction fees were reasonable, you could simply sell it to people and they pay you in cash. Nowadays I don't know how resistant it is.
Do you really think you cannot by anything with Bitcoin? Are you uninformed or just dishonest?
Yes, you can buy some items online with BTC, but almost no household daily essentials. Show me a grocery store, gas station or pharmacy that accepts crypto. There are plenty of companies selling Crypto payment gateway software, so it’s clearly not a technology limitation.
The reality is there is no consumer demand for crypto as a means to purchase things.
