I agree it would be pretty dumb to speculate with money you need.  But did you see the picture of that ugly car?  No one needs such a hideous thing.  The OP said he has a 14 year old VW, which is 6 years newer than the Camry I drive around.

In general, if you can suppress you material desires and live frugally and simply, saving and investing all you can, I think it is a sure path to personal wealth and financial freedom.  Most people would rather have the stuff, and have it now.

OP - good job saving so far.  There are other investments out there beside bitcoin.  A car obviously isn't an appreciating asset, but consider precious metals, saving for a down payment on property, or even just a boring index fund.
