It doesn't matter if you're into Bitcoin or not. If you go out the street with a big sign that describes you as a potential multi-millionaire, then you're just naive. You prioritize validation and recognition more than your physical wellbeing. If you're into Bitcoin since 2016, you should have already acknowledged that your privacy outweighs everything.
Also. The taxman is watching you.
You have just said it all and absolutely the above acquired based on the ascribe automobiles and the other expenditures actually has nothing to do with the halving.
As much as I know, the only risk involved in halving is the traumatic ness of beginners who has made sufficient profits with their Bitcoin holding.
Lot of beginners may not have that ideology to sell off their assets before the halving and gets set to keep reaccumulating during the halving on the DCA method so they could secure more values of their Bitcoin assets before the bull-run is activated just as some other experienced investors may act.
I feel they would be traumatized later finding their appreciated holding has decreased and with the tunes of fear not to have more lost counts, they may sell definitely at the wrong time which could had been better that they just hold their patients and trust the market that they will revive more better when the market volume changes by the bull-run.
The rewards of this halving may only be insighted as an opportunity for more investors to come on board and also giving the opportunities for Investors to accumulate more to their assets.
Just as you said @BlackHatCoiner anyone can actually purchase anyone of the mentioned as much as you have the money and so also, you can customize your rides of others even without being a Bitcoineers.
Moreover, such display can be conic of exposing you to dangers because Bitcoin already is an attractive treasury assets not just to thefts but to the public as a whole where they look Bitcoin holders as multi rich investors.
Aside all that reigns of halving and the bull-run a Bitcoin holder can still afford any of it as wishes.
Personally I would even assume such public broadcasting is a waste of time and resources. Real investors are not so much attracted to living luxuriously when they knows they do not have much of funds accumulated yet so they could maintain the living standard instead they keep to invest more in both accumulations and diversification until a great dreaming height is achieved.
