☑ evidence that it is better to accept the default fee amount

No.  

[academic stuff] But Psychologists have noticed that different games appeal to different personalities, and mathematicians know that different games have different % Expected Value (EV).  I see evidence that some games reinforce specific personality traits and habits.  The self-selection process (appears to me) to result in different personalities having noticeably different financial results when gambling.  I realize that it is not always easy to separate cause and effect [/academic stuff]

Some of the advantages of Bitcoin involve the remote but private purchase of items and services, in a way that does not show up on a credit card or bank statement.  And there will always be a multi-billion dollar demand for these items and services.  They include completely legal things that people want discretion and privacy when purchasing, and things that are legal in some jurisdictions but not in others.

The acquisition of Bitcoin is a separate step from the private purchase of the items or services, but the general public has been slow to recognize the advantage of that two-step process.  The good news is that Bitcoin Market Capitalization is now at approximately 6.5 billion USD, and Bitcoin wallets can be downloaded from most of the major software sites.  That is progress.

Does someone who buys a scratch ticket every day have a noticeably different personality than someone who works regularly to improve his poker game?  

Are there differences between slots players and blackjack players?

I prefer local transactions

That sounds correct to me.  

So it appears to be influenced by personality or habits.

First, if we observe the personality and characteristics of a large number of people gambling at the following games, will we notice any similarities, or any differences?

• Slot Machines
• Scratch Tickets
• Craps
• Roulette
• Blackjack
• Dice
• Poker
• Lottery
• (add your own game if I forgot to include it)

Are people with certain characteristics drawn to play some games, and to avoid others, or do we find an equal distribution of personalities among the games?

If you compared a large number of losing gamblers to the winning gamblers, would you notice any differences in personality, ability, or habits?

Is it something that we could test people for?

Are there things that we could encourage, reward, or train people to do better that would increase their chances of winning?

Bloomberg has a lifetime of dollar-denominated investment success.  To a hammer, everything looks like a nail.  Someone else will lead the Bitcoin parade.

I laughed when the pit boss said "Ashley.  I want you to take a moment and get yourself composed, and then we'll go over the rules of the game.  Are you sure you wanna make this bet of your life savings here?  I want you to know, we would never knowingly condone or accept someone making a wager of their entire life savings, but we know this is a culmination of a grand adventure for you, and hopefully the start of many more and more interesting pages."

It may be useful to remind ourselves that Bitcoin is one part of the decentralized revolution.  The parts currently (or will soon) include:

• Cryptography – private communication
• Bitcoin - decentralized monetary system
• OpenBazaar - decentralized marketplace (a blending of the best features of eBay and Torrents)
• Torrents - decentralized document distribution
• Distributed websites - decentralized publishing. Distributed websites are not stored on a single server.  The parts (including images and even different words of each sentence) are hashed and reside on multiple servers worldwide.  Publish anything, without actually writing it.
• 3D Printers and CNC – decentralized production

The old model of buying pizza with Bitcoin is still possible, but the real utility of Bitcoin will soon become apparent.  There will be many new users, and a higher price.

One option is to install OpenBazaar (and your OB storefront) on a dirt-cheap, low-power Raspberry Pi using Raspbian server, and let it run 24/7.  But if you need stealth, additional steps would be necessary.

If they release a fully functional OpenBazaar this year, it will be

My main source of income is playing internet Bitcoin poker.  I do not invest in inventory.  There are almost no expenses.  It is completely portable.  It is off the grid.

Cash is being used for illegal activities, by the truckload.

The OB interface has improved noticeably in the last few months, but it is not ready for prime time yet.

The number of users (and the price) for BTC will increase when OB is fully operational.  It will be front page news.

People will sit around the campfire and talk about the old days before Bitcoin and before OpenBazaar.

It is not wrong if you do it right.

Internet poker can encourage discipline, observation, decisiveness, bankroll management, and aggression.  

Once mastered and combined with Bitcoin, an internet connection and a computer, it can provide a completely portable source of income.

Play only against other humans, never against the house.

Do not sit at the table with your entire bankroll.  Be patient.  Pay attention to what is happening.  Classify the players by how impatient they are.  Look for a reckless opponent who bets big with nothing.  Wait until they bet big and you have a legitimate hand.  Raise them all-in.

Quit when you are ahead.  Protect your winnings.  Do not risk them.

Repeat at a different table, always with just a fraction of your bankroll.

Many successful women want to be anonymous on the internet.  

The opposite of Facebook and credit cards.
