err... how Bitcoin works, or how the speculative bubble around cryptocurrencies circa 2019-2021 worked?

Bitcoin is actually kind of useful for some niche use cases - namely illegal transactions, like buying drugs online (Silk Road, for example), and occasionally for international money transfers - my French father once paid an Argentinian architect in Bitcoin, because it was the easiest way to transfer the money due to details about money transfer between those countries which I am completely unaware of.

The Bitcoin bubble, like all bubbles since the Dutch tulip bubble in the 1600s, did follow a somewhat similar "well everyone things this thing is much more valuable than it is worth, if I buy some now the price will keep going on and I can dump it on some sucker" path, however.

For the record - the illegal transactions were thought to be advantaged by crypto like BTC because it was assumed to be impossible to trace the people engaged in the transaction, however the opposite is true, public blockchains register every transaction a given wallet has made, which has been used by Law Enforcement Agencies(LEA) to prosecute people (and made it easier in some cases).

There are remittance companies that deal in local currencies that tend to make this "easier" - crypto works for this WHEN you can exchange the crypto for the currencies you have and want, which is, in effect, the same.

Most bubbles have a peak and crash. "The Bitcoin bubble" keeps peaking and crashing and then going on to a higher peak.

Mining rigs have a finite lifespan & the places that make them in large enough quantities will stop making new ones if a more profitable product line, e.g. AI accelerators, becomes available. I'm sure making mining rigs will remain profitable for a while longer but the memory shortages are making it obvious that most production capacity is now going towards AI data centers & if that trend continues then hashing capacity will continue diminishing b/c the electricity cost & hardware replenishment will outpace mining rewards.

Bitcoin was always a dead end. It might survive for a while longer but its demise is inevitable.
