"Air gapped" is not good enough to protect your Bitcoin

Your bank notes under your mattress are air gapped - there is an air between them and the burglars. Is this air stopping them from just taking your money and spend it? If you are worried that you may forget the password you can still keep unencrypted copies hidden somewhere safe (or your passphrase), but you can also make encrypted (with good key stretching) copies on cloud services (DropBox, Mega, Google Drive, Gmail, etc.). If you keep your seed in a safe deposit box (at the bank), the bank employees can open it and steal your coins. Also, the government can demand opening of your safe deposit box and steal your gold and crypto. Archiving private keys - TLDR version

Why prices on different Bitcoin exchanges are not the same?

There is a big difference because arbitrage between exchanges is slow and dangerous due to the legacy financial system's defects. It's a high risk of regulatory problems because banks see this as money laundering. They are obligated by law to play the security theater and will cause problems to arbitrage traders moving fiat funds between exchanges. If you know how to move funds between exchanges fast and with less fees – there is a profitable (but risky) business opportunity. If our current financial system allowed for immediate transfers between participants, arbitrage would eliminate these price spreads on different exchanges. Also, there is a big difference between the futures contracts and the real Bitcoin prices. This is because there is a risk something will go wrong with the exchanges (they may not work when the futures contract expires or there will be too much volatility and low liquidity).

US dollars are backed by...

US dollars are backed by the fact that the government will put you in jail if you don't buy US dollars to pay your taxes. You can use only US dollars to pay taxes in US and other countries. This way the government is supporting the price of US dollar.

Bitcoin is drawing the interest of tax authorities in many countries

One of the things that many people don't realize is that Bitcoin is drawing the interest of tax authorities in many, many different countries all over the world. What is quite clear is that Bitcoin trading is jumping right to the front of the queue of priority tax investigations. This is easy to note by having a look at the official web pages of assorted European tax authorities, and also at the US IRS. What this article is hinting at is that tax authority cooperation across many different national jurisdictions is converging. Bitcoin proponents really aren't paying enough attention to what happens when you actually try to monetize your gains. Forget the Blockchain. Look at the final result (house, fancy new car, fancy boat, hefty bank account) instead. Because that is what the authorities will do. is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to
