after stumbling into assets with returns in the 100x-1000x range, twice, it seems time to update a bit.

How many assets have you purchased that didn't turn out to be valuable? A friend just looked up the price on a lego set that had been sitting in his room unopened since he was a kid (right after he opened it and built it...) and found that it was worth ~500x what it originally sold for. But most toys people buy and leave unopened are going to be nearly worthless a decade later.
