Back to bitcoin...

The problem I see here is that, while a great savings/investment plan, it seems to be assuming that BTC will just keep going up indefinitely at some radical rate of growth. What we have seen over the last few months should shed some light on how realistic that is. There isn't really a precedent for assuming that Bitcoin will continue to rocket up in value and double many times within an average person's life span.

I'm not anti-bitcoin growth, I'm holding some and certainly hope it will rise. But you need to be careful when everyone starts urging you to BUY! BUY! BUY! It may well be that they are trying to sell.
