you are not wasting your time with "bitcoin" as it has a good future and most importantly because it is offering something useful.
however, in my opinion you are wasting your time with your site that you are also advertising here in your comment. the fact that you are busying yourself with things that we all know have no future calle ICO/STO/IEO is already bad. not to mention that majority of them are purely scam operations created to raise funds and nothing else. and the rest are just useless that dedicating even a second to any of them is a big mistake.

altcoin pumping season is inevitable and it will happen. but like always, it will be brand new coins that get the biggest pumps and replace the old ones. if you look at the market pre 2017 it didn't look like this at all. the names were different on top. and if you look at it again in 2020 it will be entirely different again.
all the while bitcoin remains on top... as long as altcoins remain pump and dumps.

as far as legality goes and the "law", the government sets it and bends it. so we really can't say something is against the law as they are the lawmakers and set anything they want. we already have a couple of third world countries like Bangladesh that have banned bitcoin and there was no law to prevent that.
someone said a good thing: if you don't like the law makers then don't vote for the same idiots again and again...

unfortunately at this point that is not something anybody can predict. because this market is known to be volatile like an explosive, all it takes is a little bit of excitement and a couple of major resistances to break then we can easily see the next big bull run begin.
we just got out of the recovery phase to come back to more realistic prices after the undervalued 2018 drop. and the momentum is great these days. if it keeps up, then in 4 months we can easily see $30k.

the main usage of tether is for altcoin trading not even for bitcoin. there is only one major exchange called Bifinex that is doing bitcoin/usdt trades and that is only because they own and print tether themselves and have no other option ever since their banks closed all their accounts a couple of years ago.

other than that if you check all the altcoin exchanges, the major ones, all have USDT and use that because they don't want or can't add fiat.
and that is why they have been printing a ton of it in 2017 and 2018 because a ton of altcoins were created, pumped and then dumped in those two years and the market needed it.

lol, this looks just like another exchange selling its users' KYC documents on the dark market and pocketing the money then pretending it was a hack. they have good excuses for it too since they got hacked a while ago and they are linking this to that.

how many times these centralized exchanges have to sell our personal data before we at least stop using them for altcoin versus bitcoin trades and only stick to them when fiat is involved?

that is not a question that you should ask others. it is your money and we are not your financial advisor obligated to give you good advice. if you want my views, i would never touch a centralized altcoin such as XRP at any cost. i believe they shouldn't even exist in this market and we, as a community that started a decentralized market, should put an end to these coins.

profit-wise, shitcoins like ripple only get short lived pumps. so even if you were so interested in making a profit you should only get involved during the pumps not after they ended!

i was hoping more for actual examples of the actual serialization (the bytes) that are signed when sighashtype is a different thing than ALL.
maybe something like this: https://bitcoin.stackexchange.com/questions/32628/redeeming-a-raw-transaction-step-by-step-example-required

the contract page on wiki helped a lot though. and i had a mistake thinking different sighashtypes were used for certain output types not just anything. reading these links that were provided and looking at some code i think i understand it better now.
i just have to debug some code to see what happens under the hood to fill in some gaps.

i have been learning more about how transactions are signed and already finished all output types but all with SIGHASH_ALL. i feel like all the documentations are lacking when it comes to different SIGHASH types.

bitcoin.org has a "transaction guide" that explains what is signed with each type but i can not find any actual examples anywhere to understand what it means and see it on an actual transaction on the blockchain.

are transactions signed with these types even final/valid?
what is the scriptpub of the outputs they are signing?

how do you know i haven't already ask them multiple times?!
the fact is they don't accept bitcoin as payment and they don't have any plans for the foreseeable future.

the second point is still valid by the way, considering the high volatility of bitcoin.

why would i want to do that?
as much as i like bitcoin and use it in as many occasions as i can, but i still can not use bitcoin in my day to day expenses such as paying the bills and buying groceries. getting paid in bitcoin (fully) means i would have to convert it to fiat (pay extra exchange fee) just to be able to spend it!

there is an additional factor that you should never invest more than you can afford to lose. going full bitcoin means i would be risking more than i am willing to.

i prefer keeping the balance of investing my excess fiat that i don't need in bitcoin.

then you are already doing something illegal by just being here not to mention getting paid in bitcoin already, if you are really living in Bangladesh.

the altcoin market is a whole lot of mess. everyone is blowing in their own horn trying to sell their garbage to the newcomers. and the funny part of it is that all of these altcoins, specially the top ones have lost more than 60% of their value over the past 6 months that bitcoin was rising!

the correct term here is "outputs" because they are not addresses anymore. address is a concept we created after we started hashing the public key and using P2PKH outputs instead.
not to mention that technically an address is human readable encoding of the hash using base58check or bech32 encoding.

the $12300 that was hit today was only a small sign of the FOMO that is building up in the market again. i said this before many times that whenever we have a case like this days where price is going sideways, it builds a lot of FOMO potential in the market which would break out as soon as that sideways action ends.
obviously some will FOMO sooner which is why we see spikes such as this $12300 case. but it will be small since it is only a small percentage of traders who FOMO sooner.

the argument is not about what they can or can't do. it is about the cost of doing that. yes, they can also shut down the internet entirely and even cut the electricity to every home but it would cost a lot, and not just money cost!
same with printing money, the main damage is on the economy of that country but it won't stop there.

i think most of these newcomers who call these price changes "flash crash" or "pumps" aren't doing it because of the volatility. they are surprised because the "numbers" are big. otherwise if price went from $22 to $20.91 nobody would have even thought about it. why because 22 is a small number but 12200 is a big one, doesn't matter if the drops are exactly equal in size percentage wise!

this will only get worse the higher the price goes. imagine what they would say when price falls from $122,000 to $116,000. they see the $6000 difference not the 4.9%

countries are usually more willing to accept bitcoin as a commodity, security or something like that which they can tax easier and "more". if they accept bitcoin as a currency then they will have a much harder time taxing it and will definitely not be able to tax it as high anymore. that is why Japan (adopting bitcoin as a currency) removed taxes on it!

remember that them creating their own altcoin doesn't have much to do with what they would do to bitcoin though.

the "blockchain" buzzword has spread everywhere not just with random people and companies but also with the governments and the banking cartel. they also see the potential of making a ton of money and at the same time remaining in the competition.
this is their second stage of denial. the first was putting bitcoin down as too small and not a concern. the second is trying to copy it and the third will probably be the full on fight and finally it will end with their demise.

i don't think there will ever be any problems with asking for KYC in cryptocurrency space. we all know and understand the centralized services are subjected to regulations.
the reputation is ruined when they start claiming to be decentralized (like decentralized exchanges that are centralized, eg. Binance DEX) or talk about privacy (like this case) and then their actions are the exact opposite of their claims.

what news? i don't see any news, only a shitty website called CCN publishing some nonsense from the mount of a well known scammer repeating the same thing that he has been saying for the past 2 years trying to pull his identity theft scam and make money from it.
