Well to be honest, I was somewhat of a skeptic at first. Although I enjoyed winding Mr A up and ultimately putting him in his place etc, as I have said many times before, the only reason I initially bought the first time around was because I could see an upward hype trend that i was willing to best still had some way to run. (And fortunately I was right on this and made a very nice % ROI).
However, I was never comfortable with an asset that cannot be valued (as it produces no yield) but I wanted to educate, document (and also debunk) the typical objections and misconceptions that people had against BTC. I sold after the last peak at around 15K, so made great gains. I then started rebuying at 5K as I concluded the bounce back was permanent, and now have 11 coins. I have now have come around to thinking that BTC really is possibly both here to stay, also also that it "could" well have huge gains ahead in years to come.
We have seen a Bitcoin go from $1, to $10, to $100, to $1000, to $10000. Its quite feasible next stop is 100K. To me, allocating a small portion of net wealth to this is worth the possible return, not to mention a real hedge against a range of possible future scenarios. As Mr A used to say in jest "first 100,000, then 1,000,000" - ironically he may turn out to be correct yet has stubbornly and steadfastly refused to buy himself being the stubborn old man he is...
