Bitcoin is a virtual currency but there we need real money to trade it and use it or to cashout it, he don't understand how crypto works, you should tell him is similar to stocks market.
It is much better than stocks because you can spend these stocks directly. You can trade stocks for other spendable stocks as well. Much faster then the tradiitional stock market and far less labour intensive since they have to keep holdings of oil and gold or the maintenance of a large company since only large companies are the ones that mostly use stocks. With crypto even the smallest of companies can use stocks (cryptocurrency).
