I like the concept of re-balancing, but if the theory does not allow you to invest in bitcoin then it is highly flawed.
Hi, dannno! Coming back to this thread and this issue to be more clear. I actually think that Bitcoin is a fantastic speculation. If you are going to speculate, you might as well speculate on something with an absolutely, well, spectacular upside. You should take into account the risk-reward ratio and decide accordingly whether to buy, and when to sell.
For example, you say that "I believe bitcoin could possibly go to $10k - $1 mill. per coin some day". So, let's take the $10,000 figure. You have to figure out how likely you think it is that it will go to $10,000, and ideally you should have a time-frame as well, in my opinion. This "odds-making" will take introspection and thought. And you should always consider the possibility you could be totally off, because this is a subjective thing. You're predicting the future, after all, is what it essentially amounts to. But then once you've done this process, you can then make a plan accordingly. If you think that there is, for instance, a 25% chance that Bitcoin will go to $10,000 in 5 years, what is that, about 13 times, then in all seriousness that is a very good risk-reward ratio and you should put 100% of your speculative funds into that, unless you find anything else with a 13x-25% ratio like that, or better, that you want to split your funds into. So you should go all-in on Bitcoin. And then you wait for 5 years (or whatever your target time-frame was). 25% of the time, you then cash out and have 12 times what you started with. 75% of the time, something else happens. A big part of your job as a speculator is determining what that "something else" is. So, when you first buy the speculation, you should put in a stop order. You should decide: if it goes under X amount, I'm selling. I don't know if there are any Bitcoin markets which have the feature of stop-orders, but if there are, you need to put one in! You do not want to have to be wringing your hands and deliberating in a messed-up emotional state at the time of a crash. Just have a stop order. It will be automatic. It will save your hide.
You may also want to put in another, higher stop order as it goes up to lock in your gains at a certain floor. This is optional. It will depend on how volatile you expect the speculation to be whether you want to do this.
This is my advice as to how to go about speculating in Bitcoins, or anything else.
But the more important advice, you already gave, dannno:
only speculate with money you can afford to lose! This is essential! The money that's precious to you, the money you've worked hard for, the money that you want to save and protect, you should not speculate that money. You've worked too hard for it to risk it all in some scheme to triskadecatuple it.
The money that you
can afford to lose, speculate to your heart's desire. This money is your Variable Portfolio, or your Speculative Portfolio. But you keep that separate from your Permanent Portfolio, which is where you put all the money you want to keep safe.
So there's two piles: Speculative Portfolio, and Permanent Portfolio. I personally have no desire to speculate right now, and thus buying Bitcoin in hopes that it will go up in price is just not appealing to me. Bitcoin belongs in the Speculative Portfolio. For someone that has no Speculative Portfolio, there is no place for buying large amounts of Bitcoins.

That brings me to why Bitcoin does not fit into a Permanent Protfolio. The Permanent Portfolio is designed to protect your money in all different economic climates. There are four general climates: Inflation, deflation, prosperity, and recession/depression. It has an asset that does well in each climate. Gold does well in inflation. Bonds in deflation. Stocks in prosperity. And cash smooths things out in a recession. Each one is causally linked to its climate. There are solid, logical reasons to believe that they will
always perform well in their given climate. Empirically, extensive back-testing shows no times in which they didn't.
So, with 25% in each, you're prepared for whatever comes. And the really nice thing is, it turns out that the assets performing well do it much more powerfully than the ones that do poorly. The asset going up in a bull market might go up 100%, 200%, or even more, whereas the one going down will go down 20%, 30%, or maybe in a bad crash even 50%. But the strong asset will far outweigh the weak ones, and so it will carry the whole portfolio.
So you can see why Bitcoin does not fit in. In which economic climate do we have good reason to believe it will go up? Prosperity? Deflation? Inflation? It's not clear, is it? Nothing against Bitcoin; the same is true for virtually all assets. Only the assets powerfully linked to a particular economic climate are interesting for the Permanent Portfolio.
