People think you should buy bitcoin because the price might go up.

But the real reason you should own bitcoin – especially in your retirement portfolio – is that it’s a bet on a monetary revolution.

Crypto assets are all about cutting out the banks, middlemen, financiers and academics who control our current monetary system.

The monetary policy of today’s world is a mess rife with conflicts of interest and bad incentives. Every country does it similarly. And government is always tempted to print money. It punishes savers and rewards borrowers.

A well-constructed cryptocurrency, on the other hand, has a hard cap on the number of “coins” in existence.

There will only ever be 21 million bitcoins. You can’t change that number. There are a little more than 15 million available today.

So if we’re looking at bitcoin as a competitor to the dollar, there’s no contest. The U.S. government, for example, borrows more than $1 million each minute… printing money like crazy all the while.

That’s why bitcoin has risen from around $0.005 in 2010 to more than $5,000 today.

Bitcoin is a call option on a future where it is mainstream money. You don’t sell for double or triple what you put in; you hold on and hope it keeps going up. Less than 1% of people own bitcoin today, and if it becomes mainstream money, today’s bitcoin owners may be tomorrow’s new 1% of earners.

But it’s not just bitcoin anymore. There are hundreds of interesting cryptocurrencies out there – all competing against each other, sharing code and breaking new ground.

Here’s what’s really revolutionary about it…

All these “coins” or “tokens” (digital assets) have their own funding mechanism – the initial coin offering, or ICO – in which well-run projects raise tens of millions of dollars each week… hundreds of millions in many weeks, actually.
