well, the way i see it, if I just buy and hold bitcoin, I get absolutely nothing from this as far as experiences or future memories are concerned.
Let us hope your future memories are not plagued with people pointing out the financial folly with respect to rationalizing such purchases.
if bitcoin becomes a pile of digital dust (hopefully, not), then at least you can remember those days
... where you bought low, hodl'd, and sold a fraction of a Bitcoin at some future date at way more than you could have imagined.
So, I will try to use something for mining and/or learning, maybe a fancy stick, or a needlessly criticized "bitcoin computer" or something else entirely.
As long as you go into it with the understanding that you are not going to make back whatever you spent on the device - not placing any value on any "fun" or learning you would derive from the purchase - go hog wild !
gosh, someone is grumpy on a weekend...

I have seen many investments turn to an absolute manure, but you have to be in risky investments to have a good return, as you know.
I am quite enjoying my S7 so far, and did enjoy Sp20 tremendously, but I could never host SP30 at home-had to do hosting.
regarding "making some"-it largely depends on a timeframe and on whether you count in BTC or in $$. I always count starting in $$, not BTC, it makes everything simpler.
