I agree with the first statement but not the second. Why would you ever consider trading back to fiat? I would rather see Bitcoin drop to 0 before trading back to fiat.
buying nice things ?
I'm pretty sure many are getting back quite some life changing amount and they will consider cashing out a part for ... see above
I prefer to buy things i need over things that are nice.
For now, i'm satisfied with my current life, so no real need to change it.
At least not this early 
that's exactly what I'm talking about: for some it's not early anymore and they are sitting on a 50x or 100x
and btw buying things you need is nice as well... isn't it?
