first you need to understand what a QC can do in plain english.. without out the mystical multiuniverse mumbo jumbo they try to spew out to hide their technologies secret ingredient..

and so, the fundamentals..
normal computers work by understanding that if it stores or transmits a voltage that is considered a binary 1.. no voltage is considered binary 0

QC is NOT about bending time/space or entering alternate universes, it is simply that the voltage is variable allowing more possibilities

so instead of a byte only having 256 possibilities of 00000000 to 11111111
a qubit can have more. 00000000 to 33333333(using a 4 position qubit) which is 65536 possibilities for the same 8bit of voltage variants.
all because instead of just 0volts or 1 volt. it can be measured that
0volts=0
0.33volts =1..
0.66volts=2
1volts=3
..
1 binary bit has 2 "super positions" 0-1
1 qubit has 4 "super positions" 0-1-2-3 in the example above(though some facilities are only playing with 3 super positions 0-1-2)
..when translating a single qubit position into binary can be seen as different things(i wont waffle into that aspect)

now with that said. although there are now about a dozen different facilities playing around with QC.. they are still looking at what can be done with it.

things they do know is that if they put in a binary logic problem they are limited to the efficiency of QC to about 2x.
this is because the result they need also needs to be binary so that a binary system can accept the problem is solved. and as such they can only play within the constraints of binary. and thus the only thing they can do is use half a qubyte (0000), for the systems with 4 positions to do what a binary system needs a full byte(00000000) for

so first things first.
binary logic problems such as block hashing is not a worry. firstly because not only are QC limited to a efficiency of 2x per operation.. but also the power of the QC systems are no where near as powerful as the network hashing rate.

for instance the largest binary super computer is only able to do a few terrahashes of bitcoin mining a second..(1 quadrillion ops a second)

 yet the bitcoin network is 24million terrahashes.(24sextillion ops a second)
yep 24million binary supercomputer facilities are needed just to match bitcoin mining

and a QC systems are no where near even capable of doing the same amount of operations per second that the largest binary supercomputers can right now..
so its not a threat.
yep it will require far more than just a dozen QC systems just to match ONE binary super computer and then 24million times that again to match bitcoins hash power. so relax, nothing to worry about any time soon
bitcoin ASICS will exceed the hashpower of QC for a long long while

...
now thats all said.
QC are not great at binary logic problems when it comes to efficiencies. but where they do prosper is in the realm of 3D. basically vectors
which is something that legacy bitcoin private/public key conversion does rely on.

which is where a 4super position bit can using 8 bytes have 65536 possible variations instead of just 256.. meaning that its an efficiency of 256 times better at brute forcing a privkey but only 2 times better at brute forcing a block hash

and yes.. if your re-using addresses which give away parts of the answer after use. a QC computer can brute force the answer 256 times faster than a comparable binary pc.

solve spam attacks? lol
spammers spam because they want to spam. why would they decide to debloat their tx's.

spammers will just stick to spamming and no matter how many people use segwit, how many pople use LN, how many people use schnorr a spammer will still spam onchain.

what you should say is that mixers can compress their bloat of their batch tx's, exchanges can compress their bloat of batch tx's and save themselves a few sats per byte.. but stopping spam attacks.. thats a laugh

replace your world "value" for price..

bitcoins underlying value has been on a stable incline and has slowed down due but still on an incline, due to bad devs's who thought fee wars and 2nd layer banking are great..
fee wars and 2nd layer banking have made more bubbles in the speculative price. but not the underlying value

the price however is the bubbly bit that expands and pops all the time ontop of a value water line.

until you understand the difference between value and price. it will be hard for you to really analyse the numbers in any way 

they have no clue
'a payment gateway, such as Bitcoin, Litecoin or any other cryptocurrency recognized by the department, using electronic peer-to-peer systems'

...
a payment gateway lol.
crypto's are not a payment gateway
crypto's are a currency.. a gateway is a business/exchange that handles and converts the currency to a countries legal tender

the wording alone of the quote makes me feel the bill wont hold much weight, as it doesnt make sense in reality.

dont just fork bitcoin. learn more about crypto currency, find solutions to every day problems that available cryptos dont solve. and then code something from scratch to meet the niche.

just forking bitcoin is not inventing anything or solving anything,,
there are already over a dozen forks of bitcoin in just the last year alone. you might aswell not make another fork and just join one of their teams if all you want to do is market a coin that has no extra features

best way to get recognition fast. is to find some ready translated and published stuff, which has errors or just bad use of comparative words and then show your corrected version, to show off that you are better.

post it in the native language you want section of this forum and ask the native speakers to reply on which version they prefer, which made more sense to them.

that way you can show feedback that your native tongue speakers can understand what you write

nah
that super computer is meaningless
the bitcoin network hashrate is 24million times more then the super computer
yep 24million terrahashes

well 1hash=~1300 operations a second (flops)

a quadrillion operations a second is less than 1 terrahash
..
not much these days.
though the numbers are guesses and estimates and not an exact science as you will see via the quote below

we are well past the days of CPU mining. and well passed the days of 'super computers'
ASIC's are way way way more efficient and cheaper than a PC/supercomputer

after all you can buy a 13terrahash miner for only a couple thousand dollars

visa/mastercard hate their CREDITCARD customers using it for bitcoin, because the majority of them do the chargeback scam to get free bitcoin.
also by thinking that banks should offer a service to manage accounts defeats the whole purpose of bitcoin.
but goodluck if you really think that banking rules are good for bitcoin. im guessing your ideology is not economic freedom but 'look ma its legit, buy some to push the price up. so i can sell back to fiat and live a richer fiat life'

all they are offering is a encrypted webspace to store private keys

but if you have your private key wrote down on paper, you dont need the service.

some will say its to protect you incase you lose the paper.. my reply is but where are you going to store the password to access the banks webspace, oh yea paper... same risk

as for the risks of typing the private key into a browser, there are risks of people having viruses(keyboard loggers, browser extension trojans) so its much safer to have a paper wallet than some online storage that some hacker can snoop on via your keyboard taps.

after all jennifer lawrences nudes were real safe in apples cloud(sarcasm) which even the FBI couldnt hack.. wait, i remember seeing her pics.....hmm.

but oh well, with thousands of people thinking that putting funds into a co-signed address with a second party(LN) is bitcoins way forward. i guess you might aswell put your private keys online. afterall, versabank promise they are only asking to hold your private key and not co-sign your funds or blackmail the funds by denying a co-sign

no exchange should ever have a privkey online. there are many ways to still service people without having private keys on their server
no exchange should have peoples passwords stored in clear text.

but with that said, most exchange hacks were never hacks, just plausible denyiable excuses for the exchange owners to take the funds themselves and point the finger into space at some distant galaxy where anonymous hackers cant be found

the PRICE.. is not 100% VALUE

imagine it like a bathtub of water..
as the waterline increases steadily(true value) it stirs up the soap(speculation) and you see a load of bubbles above the water line.

when the bubbles burst, you still have the water line.
the water line is the true underlying value, the bubbles ontop is just the vapour/air ontop that cannot carry weight and will burst if peopl poke at it

and watch all the chargeback scammers abuse that, and then after a while see bread/simplex remove that 'feature'.

haven't they realised the reasons most services don't offer credit card purchases. anyway goodluck to their profit/bottom line

real estate is a bubble investment
yes houses are real. they exist. they have utility and function.. but the price.. well thats the bubble

when a price increases not due to function. not due to cost of creation. but purely due to speculation... that is a bubble

saying something is in a bubble is not saying the item/asset is fake. its just saying its probably over priced because there is no good reason to explain the price compared to true value, and its likely that the price is gonna burst. and go down to a lower level that can be explained compared to true value

usually bubble is screamed out at the end of a bull(up) and about to go bear(down)

volatility is not the issue.

for years merchants accepted bitcoin because they used bitpay and coinbase that converted it to fiat at receipt so when a shopping cart showed $100.. the cart converted it to a bitcoin amount to display to customers and then the cart service gave the merchant $100, within a allotted time.. thus never a problem

the math example by avikz is wrong due to avikz showing a silly example where the seller waited until the price dropped before converting.
firstly
merchants don't wait
secondly
if your going to wait your not going to finally give in and sell on the worse day of the week, so that example is wrong.
funnily if the seller exchanged on day 3 - $14200 he would have been $178.60 UP..
but yea aviks selective picked an obscene scenario, to make an obscene point

the problem is not price volatility.. the problem is the cost to do the transaction (the tx fee)
also bitcoin is not good for real world brick and mortar merchants with checkout lines, where it takes 10mins+ to guarantee the payment is not reversible.
its like watching an old lady infront of you counting out pennies for 10 minutes, resulting in bad customer service and complaints by the other customers in the queue waiting

bitcoin had a very niche market for online products and services that needed to be delivered and as such allowed time for confirmation before dispatching products.
but it did not work well for small items of under $100 due to the fact that the TX fee was growing to a few dollars just to make a trade.

which could have been avoided with simple code in the form of a tx priority fee formula.. but instead devs just went ahead, lets fees spiral out of control to then advertise their banking2.0 second layer services.

though bitcoin cash is not the chain that merchant tools follow right now and thus those wanting to spend bitcoin with merchants wont get the result that they want by moving bitcoin cash about.. i do have to say this

segwit chain is no better either. merchants have dropped using segwits chain by the 10's of thousands of businesses..

but anyway, reading your quote.. are you trying to say that bitcoin core has a legitimate claim to the bitcoin brand.

if so then you have failed the true understanding of bitcoin.. NO ONE should have claim to the brand.
but if you want to defend that core own bitcoin and any other team is just counterfeit. then you have given decentralised control over to an organisation who pretend to be random people..

what if coinbase decided that segwit core was the code that is not anything like the legacy bitcoin ethos and thus merchant tool services like coinbase and bitpay took segwit off their listing..

what if there was a big mega bug that was a threat to both segwit and x2 block formations. and both sides had to downgrade back to legacy block formations and transaction formats.

think beyond the team organisation defence and think about the utility and functionality.. because right now
segwit:
does not allow good flow of transactions onchain
does not meet merchants needs of cheap transactions
does not do what bitcoin was suppose to do that it did do in 2008-2014

right now the community is stuck at the(using social media analogy) myspace vs AOL members area.. it has not even got to the facebook era. in short w are still at the innovation stage, not the mainstream utility stage.

please dont reply with a segwit/core standard scripted defence . and think only about the utility of bitcoin and what is best for utility.. not whats best to kiss dev teams ass.

after all merchant tools like coinbase and bitpay could by utility and functionality decide that segwit is not the bitcoin advertised in 2008-2014 because merchants cant really use the segwit based chain due to many many reasons. and as such is affecting merchant tools services profitability.
even right now 'chuck' lee is advertising the hell of making litecoin the merchant tool coin. and as such litecoin could become the facebook of crypto, leaving all bitcoin variants as being the myspace/aol stuff left just for history books

think beyond the dev team battle. think beyond the kissing ass of core. think about whats most useful for the community

P.S i dont care about the team game drama.. i dont even care about which coin is the highest price. to me its about which coin is most meeting the original bitcoin ethos of allowing people to transact without barriers of entry and can be best suited to help the unbanked and those just wanting to cross national borders unhindered by the banking system.

bitcoin exchanges do NOT have 16m+ coins holding a resistance. most exchanges are trading in hundreds or thousands of dollars per order, NOT millions

thus the price is fragile and does not show real 'value'
thus easy to manipulate one/two popular sites and let the sheep on other exchanges react and follow blindly.

there will always be news. but how fragile the exchange resistance points are. are the real reason the price can move so much

my assets were at over 3000% in december, based on my very old original purchase price (yep i have been invested for a while)
and went down to about 1000% this week.

but still in profit holding.

i did buy more this month too seeing as it was the january sales period.. seeing as the prices were low id b stupid not to have

facebook is not stopping people making comments/posts about bitcoin
facebook is not stopping people making groups about bitcoin

facebook is stopping the 'suggested ads' that advertising the scammy investment schemes to avoid liability of suggesting that people shoul invest in the HYIP's and fake ICO schemes

bitcoin has not been bitcoin since 2014.

as soon as one team branded it and took ownership of it, saying no other team can be bitcoin. it no longer became bitcoin.
the point of bitcoin ethos is no one should own the decisioning power.

then from a technical bases, whichever codebase looks most like the bitcoin codebase prior to 2014 is the most closest to what bitcoin should be
and im afraid to say segwit codebase has far more lines of code that differ, far more rules that differ. far more address structures that differ, far more network topologies that differ.

that said the population will follow whatever path the exchanges/merchant tools(shoppingcarts) accept, no matter what the code/team brand is
so it ends up being that the sheep will follow the popularity, not the logic.

pre-empting standard core/blockstream defender posts
1. i dont even think BCC is bitcoin either because of the lack of merchant use from bitpay/coinbase, where merchants advertise "we accept bitcoin"
2. many will say i have been team Ver because i have been opposed to team core since 2014. but over the years team core have pigeon holed me as team gavin, team hearne, team ver.. because they cant grasp that im defending bitcoin.. not a team(on any side)
3. if you trusted a farmer for years that they are the only source of chicken eggs. if they hand you a duck egg and say its a chicken egg, does not make it a chicken egg. so take your farmer defense hat off and look at the egg
4. if your still defending a team, you have already lost the bitcoin debate
