That fuzzy feeling you get when you think about thanking hard working farmers. And that true patriot sprit you feel when you thank the first responders. These are all the result of propaganda. Essentially brain washing. I am not saying having such feelings is bad, but rather without the propaganda you probably would not have those feelings. So you are right to be cynical because you might actually get the same feelings about sandwich makers if there was a credible propaganda campaign for them too.

I dont think its practical to replace fiat currency with crypto unless there is some offline version of it as easy to spend as paper money. In real life and in most places around the world there may be power outages, poor or no internet, ignorance about using technology. But in all these places people need to buy food and conduct business. Crypto isn't really a substitute for this yet.

I am not sure what you mean by . Can you give me an example of bitcoin being fair or unfair vs USD being fair or unfair?

Just to follow up on this topic here is a possible candidate for the type of captcha that could be used:

It intentionally requires just a little more brain power to solve than other captchas.

It is great that you are taking this tweet so seriously. It was clearly a well thought out and well timed broad side to the entire cryptocurrency world. Not exactly what this president is known for, so i suspect this is a policy with support within his wider administration.

I am not sure why everyone is so enthused about a giant corporation making a massive bid on a proprietary crypto currency. The whole purpose of crypto was to decentralize currency and remove authoritative and centralised controlling bodies such as multi-national corporations. Also some say this is good for bitcoin because it will bring attention to crypto currencies. But Facebook has a track record of bungling new products, ie the Facebook Phone, and would abandon this whole endeavour like a hot steaming pile of turd if ever investors became worried that it was underperforming, bringing too much controversy, threatening other investments, etc. And after its likely failure, it will leave all those people who were newly introduced to crypto though this rollout the perception of crypto as being a failure.

Congratulations on your new update. The crypto gaming world appreciates your innovation and variety and uniqueness of gaming options. 

There has been discussion before about proof of human work coins (https://bitcointalk.org/index.php?topic=1966878.0). A coin based on proof of human work would not necessarily be a full fledged currency like bitcoin. Rather it could be used in similar ways to points, incentives, free trials and free usage tiers in a way this is anonymous and does not require each adopter to create their own implementation. This proof of work coin would basically be earned by solving captcha type puzzles and could only be spent once. I believe currently, Google's select the squares where the image contains an X, Y or Z is a great candidate for the type of puzzle. A couple use-cases would be:
An anonymous online service who wants to provide a free-tier access, but also wants to prevent abuse. The online service would simply charge users this human-proof-of work coin for the entry level tier. They would only need to implement the existing wallet for this coin instead of developing a whole new scheme for themselves.
An online crypto-casino could accept this human-proof-of-work coin as an alternative to a faucet.
However i do foresee potential abuse vectors, such as human captcha solving farms. But someone would either have to pay these farmers to generate the coin for them, or the farmers would trade the coins for other currencies . This would give the human-proof-of-work coin a monetary value. Small perhaps, but that value would simply be the basis of the value of whatever free access is given. So a person who wants to access a website who accepts the human-proof-of-work coin could in theory buy some from the "farmers market" at their market value, or simply produce it themselves for free.

The professionals are playing games where they can make a statistical advantage for themselves. Most crypto games do not fit into this category. However, I want to make a defense for crypto gambling.  What they do offer is entertainment to the overwhelming majority of gamblers who are just out there enjoying themselves. And with super thin house margins, provably fair games and easy deposit withdrawels, crypto gambling has its advantages to more dodgy brick and mortar options.

Coin Ghost is going to be a very different kind of crypto game. There will be a ghost wandering around a tomb trying to snatch your coins. To maximise your payout you want to place the coins as close to the ghost as possible and then letting him wander as far away as possible. I will be posting the provably fair seeding event here probably by the end of next month. https://i.imgur.com/ot2tm1K.jpg
