Bitcoin technology is still one of the most used technology in crypto currency. Then you are asking why bitcoin is still expensive than any types. The answer is of course, bitcoin developers and blockchain technology still continue generating coins through mining. To have a huge amount of money, you need a sophisticated tecnology to process the algorithm of mining to create a coin. And the support line is still getting by bitcoin tech.
bitcoin is not the most used tech, its the most promoted tech.
take fiat
people think the dollar is the most used currency because people compare and measure oil and world economics to the dollar. but in reality only ~400million out of 7.5 billion people actually use dollar.
where as in india/asia BILLIONS of people use chinese or indian currency.
the bitcoin specific tech for mining (the sha256 hash algo) has not changed in 9 years. so there has not been any change to that.
asics. which came about in october 2013 are not bitcoin specific. they can be used on other coins too.. so you cant praise bitcoin devs for causing a price increase in october 2013. as the bitcoin devs had nothing to do with ASICs.
flipping the debate. with mning costs coming down, would you blame the bitcoin devs for this march onwards dip? nope, ud probably blame the asic manufacturers for making cheaper more efficient rigs. (hope you see my point)
..
i personally have a nice hoard of coins from as far back as 2012. so dont get me wrong i love the principles of bitcoins ethos 2009-2013. but since 2013 the innovation of bitcoin specifically has changed/dwindled/ been sidesteppd by other projects/networks.
i am not someone that does the over promoting under delivery proaganda bull crap of speculative grabbing people to cause a hype for some 10 minute ATH price drama. i am a realist. i find it better to call out faults/issues and be realistic about the situation and for people to know what truly lays underneath the tech, the price, the value.. so that these things can be dealt with
for instance. the price.. there are 2 aspects that give bitcoin nice supprt. the mining cost and buyers remorse. if bitcoin changed the mining algo to PoS or as other put it 'asic proof'. then there dies one line of support. leaving only buyers remorse .
and then the speculation of utility which causes the volatility bubbles ABOVE value(above support). which like waves can spike up, then correct itself down causing panic and drama.
so if PoS came to be part of bitcoin specifically. or 80% mining pools stopped mining because the cost increased but the utility of the network deminished because people were using LN/altcoins instead. then the support line for cost of creation would drop. because difficulty would drop and only 20% of miners could afford to carry on at a lower price
