This explanation misses a lot. When I watch an advert a second time, it seems to pass a lot faster than the first watch. My brain however has not changed at all. It seems that novelty is the main factor causing the perceived slowdown of time and that lack of novelty (less things surprise me as I age) makes time seem to pass more quickly. This also explains why staycations pass a lot faster than a trip somewhere new.
The real problem is how much the bank earns off the interest it charges you throughout your life while it had to do what?... create new money from nothing into the money supply with special permissions given to it by the government. This is why housing is so expensive to begin with. This bullshit needs to stop.
Probably depends on your aversion to losing it all. If it's a dollar go for it. If it's 100 dollars, again, take the bet. If it's your life savings of 50000 dollars and going to 0 would be worse for you than 70/30 doubling your money, you don't want to go for it.
This means that when the coinbase rewards run out, the fees pay for the mining. Small fees, keeping the network useful, for billions of transactions (bandwidth and storage costs decrease according to Moore's law). With this final state, individual on-chain transactions would not take much energy at all.
