Hello! I'm the owner of that coin, and I can answer any specific questions that you may have. As a high level explanation of this coin, back 2013, Worldcoin was a coin that was released that was a fork of Bitcoin. However, it had some changes added to it's "magic numbers" that determined block times for the application. The original developer for the coin theorized that block times did not have to be 10 minutes and could be MUCH lower. IIRC, block times for WDC were 10 seconds and full approval was reduced to maybe 3x new blocks after confirmation. This is important because it made WDC fast. In fact, the purpose was to make it far more viable than BTC or LTC and it could be something you could use for real-world transactions. Worldcoin was released before 2013, however, around that time new services were being built around the coin and it was becoming quite popular amongst alt-coin enthusiasts like myself. Towards the end of it's life, a crowd funding campaign ran by a few of the lead developers raised funds to make a payment processor and purchasing company like Coinbase. It actually released in beta, it worked exceptionally well, and there was rumor that the same exchange was going to launch a coin-for-coin trading exchange as well. However, the success for WDC relied heavily on the success of the Coinbase-like company. Allegedly, the investment BTC in the company was hacked and stolen, and with a large loss of almost all funds, the exchange closed down. WDC literally crumbled over night and it never recovered. So where do these coins fit in? Well, the BTC Casascius coins launched about a year or so earlier, and the fad started for cryptos to have some form of physical coin. One of the key developers for both the coin and the WDC open source project made these 500 coins. They were sold in late 2013 and delivered in early 2014, IIRC. The thing is, right after they launched, WDC collapsed. I was good friends with the maker. Initially he limited the number you could buy (5, I think) which I bought that amount but after the collapse of WDC, he sold me his remaining lot, which wasn't much. So that's the story. I doubt it will ever be recorded in the record books but in the much earlier days, BTC had a few coins that almost gave it a run for it's money. Had the exchange not shut down, there's a chance it could still be a powerful coin today. I do know that there were engineers that were tinkering and changing the fundamentals of the coin so that they could improve confirmation times and restructure the way the coin would work so it could be used even more easily and quickly on cell phones. Alas, WDC never got a chance to see that happen once the market crashed.
