I don't believe I'm a slow learner, but it took me about 1 year from first learning about Bitcoin to becoming comfortable enough with the technology to speculate on it.
I honestly believe it will replace Gold as a store of value, but it will take a very long time for the general public to understand it enough and/or trust it enough that they'll sell any amount of gold for bitcoins. But when they do, perhaps in a slow process that peaks around 15 years from now, the value of a single bitcoin could end up somewhere around $300k.
I personally estimate the likelihood of this being around 10-15%. So yeah, I'm still buying more today.
