> These are 3D virtual world environments and people are using (VIRTUAL CURRENCY) to build an online economy. They are trading property, buying virtual artwork and creating galleries, setting up clubs and meeting spaces, etc. What you're describing here is Roblox (2006), which was launched 2 years before Bitcoin was conceived, and has attained a market cap of >$50 billion without any cryptocurrency nonsense. Or Second Life (2003). Or RuneScape (2001). Cryptocurrency doesn't enable online trading with virtual currency -- if anything, it's dramatically _more_ difficult to use than either real plastic, or virtual currency sitting in a SQL table. What it enables is theoretical trust in a shared ledger (handwaving that a Sybil attack isn't attempted by any of the massive mining pools); but this trust is assuming you're a computer scientist capable of auditing the clients and contracts. Yet, even professional programmers have lost hundreds of millions of dollars worth of crypto with programming mistakes and security flaws in their smart contracts and clients! If even professional crypto software developers can't take advantage of cryptocurrency's supposed benefits, how are the players of an online game supposed to? The answer is of course that they have to relegate trust, in the same way that online shoppers relegate trust to Visa/Mastercard. The important difference being that only Visa/Mastercard guarantee your funds are returned if you're defrauded.

No, I'm not describing Roblox. Roblox is a great game and has many great characteristics, but this is bigger and broader than that. Sybil attacks would be detected in an open network first of all. If you can pull it off, I invite you to try: there's hundreds of billions of dollars on the table protected by nothing but cryptography and game theory. Knock yourself out. I'm sure all the people in this space are idiots and haven't seen the holes you claim are there. I'm old enough to remember when using a credit card was a hassle or seen as predatory on consumers and many people either refused to use credit or accept credit in their businesses. For several decades using a credit card wasn't any more convenient than using cash or check even. Over time, the scanners got better and faster, Visa and MasterCard integrated with ATM debit cards, and then mobile phones and swiping plugins enabled it all to get better. Now it's ubiquitous. But that ubiquity will make it all the more easier for merchants to adopt crypto. It turns out there is already crypto insurance protocols like Nexus Mutual and Cover that will cover you if a loss occurs. Insurance is really just a business problem that is easily fixable. On the plus side crypto is far more secure than Visa or MasterCard, because it works on public/private key cryptography and you simply sign a transaction rather than enter your name and address and all the same information you'd need to commit a fraudulent credit card transaction.

The point is that no-one needs to adopt crypto for payments because the existing payment platforms work fine, better than crypto. Making transactions immutable, requiring users to maintain perfect IT security, currencies swinging in value by 20% every time Musk tweets about them, etc, are regressions.
