Bitcoin is a crypto digital investment asset compared to gold, a physical investment asset. Both are very valuable.
If you have 10 ounces of pure gold bar, you can sell it and get close to $19K, or you can pawn it and get a smaller amount per the terms you negotiate.
If a person has 1 bitcoin btc, there are more options.
1. Transfer the bitcoin to Coinbase, sell and get over $23K which will be sent to the person's bank account through ACH
2. Deposit to BlockFi and borrow 50% LTV, with the $ amount sent to the person's bank account through ACH
a. Or, don't get a loan and earn interest of 6% APY (payable in btc)
3. Transfer the btc halfway across the world to another person (company). The full $23K+ value will be transferred and the recipient can redeem the value, locally. This can take place in a matter of minutes, even over a great distance, say from USA to Singapore.
Bonus: The person can use the 1 btc to purchase all kinds of stuff from places that accept btc, i.e. NewEgg, buy the latest MacStuff.

There's a lot more stuff going on in the cryptos financial ecosystem, but only the participants are aware and no need to mention here.
When someone is laughing that bitcoin and cryptos are not digital assets, they are clueless or too stupid to understand.
