it is a nice thought but it is unrealistic because there are a lot of forms of money and a lot of currencies belonging to different countries and different governments. these are not just going to disappear or even go down without a fight. and people are still happily using them.
bitcoin is more like an additional option.

it is trading we are talking about not gambling.
your money won't just disappear if you make a mistake! when some altcoin invested in goes down for example your $200 will become $150 worse case scenario but you can learn from that mistake and never repeat it and make that $150 back to $200 and then more.

Auto Buy is exactly as its name suggests: Buy Automatically.

how it works depends on the platform or maybe the bot that you are using. but generally speaking it is a set of "conditions" that the user can define so that when they are met the program (bot) executes a buy order instead of him.
for example you say "If price <$4050 Then buy"

there can be a lot of these "Auto" stuff in bots which make things easier and more automatic.

ViaBTC was not even a proper exchange with any volume. they only gained some remote popularity and their name was heard ONLY because of bitcoin cash which they listed first and remained the only one listing it for a long time.

P.S. don't confuse ViaBTC exchange with ViaBTC mining. they are two separate operations. the exchange was closed.

they are not the first!
there has been a lot of talk and the same "consideration" to start a digital currency using the bitcoin blockchain technology. you can search among the news to find all of these cases of different countries, different banks or even some financial firms talk about creating their own crypto currency.
they all just going to be some ledger they use for their purposes and won't be like bitcoin at all.

if bitcoin were centralized or someday become centralized then it will be the death of it. it may not exactly die and disappear but i am sure that most people will leave it behind and move on to the next best thing that remains decentralized. it can even be litecoin which is very similar and still decentralized.

one of the reasons people are interested in bitcoin is the decentralization.

for future reference:
whenever there is an airdrop, a contentious fork,... or generally anything like that which is giving you free new coins, all you need is your private keys. so no matter what wallet you are using, try to figure out if you have access to your private keys or not. if you have then you can receive all those airdrops too. if not then it is impossible.

when we are talking about altcoins it is not about "mass adoption" it is only about how they can become more expensive or in other words how they can get more pumped. and being GPU mineable is a good perk in my opinion. look at ETH for example. one of the reasons why it even became popular was because of its mining.

there are two huge issues with this type of things.
1. following others like a sheep and not understanding where they are going which you also follow, is not a good idea ever in anything not just in trading. you have to understand what you are doing, what they are doing so you can just see, take notes and bend their strategy to your own understanding and follow your own path.
tradingview is already a good platform that many share their views.

2. in my experience nobody really shares anything that is really valuable. and whenever "follow other traders" is involved you see their goals for sharing is to pump something so they can dump it on you.

that doesn't make any sense at all! usability of a currency is defined within the boarders of the country not globally. of course being able to use it globally is a perk but "citizens" don't care as long as they can pay for their daily needs with their currency at hand!

and i assure you there are a lot of other currencies such as USD and EUR before they "flip for bitcoin".

this higher price and huge volume only shows that Indian know the real value and the potential of bitcoin.

i have stopped paying attention to what these people say about bitcoin. both the negative ones and the positive alike. they are always full of themselves trying so hard to convince others about something they do not understand at all or sometimes have little understanding of.

in my experience they are just abusing the media to their advantage. as i said both positive and negative alike. they say things that suits their own behavior in the world and in bitcoin market.

why do you call it "bluff"
it was some reality about banning ICOs and also closing exchanges then there was all the FUD about banning bitcoin and mining and all kinds of weird stuff about China and bitcoin.
and none of it matters at all. even if all the FUD were true, the price would have came back here just like it has now! these things can not affect the free market for long.

you should first think what kind of demand you want.
so far it has been mostly the speculator's demand type. where more people come in and start investing in bitcoin and want more money out of it. and there is nothing stopping that as long as bitcoin is on the rise. in other words it will be like this for years.

the other type of demand is what you point out, the demand as a currency. for that i am afraid an stable price is needed most. because when people feel 1 bitcoin which is worth x today can be worth 100x tomorrow they are less willing to spend that as a currency.

logically you should always try to get the best deal of any time you want to buy bitcoin. that best deal is known as the "dip" where price takes a little dive like it recently did and price was lower than it should have been. meaning lower than the real value and even below the resistance line.

but generally you should buy bitcoin anytime you have some money and you want to invest it long term. for example it does not matter if you bought at $500 or $600 last year you would have been in a huge profit already if you did buy at any price!

it doesn't matter.
the demand is defined as the total of all these people. and so far that demand be it more traders or more holders or more spenders or anything else has been increasing which means the price is increasing with that also.

the "effect" or the price going down happened only because people like you are too lazy to check the validity of the news and just believe anything that they read online probably by some brand new account on bitcointalk!

bitcoin was NEVER banned in China!

the transaction issues are usually from the coin itself. they either have broken blockchain, some 51% attack, sometimes their wallets are buggy and needs fixing and lots of other issues which makes the deposit/withdrawals in different exchanges long.

also make sure to check the required number of confirmation in their website for each altcoin. some of them with crappy blockchain require a huge number of confirmation which obviously takes a lot longer.

i think they removed it again!
at first it was active for only some users, probably active accounts there. which was activated for me later when i claimed a couple of times and hung around in the site some more.

but now it disappeared again! although there is a link on top of the page in yellow rectangle giving me the link for mining. so maybe they moved it there.

it is not a hard fork it is just a fork from bitcoin!

it is not the first one either. there are already a couple of them around. off the top of my head i can name BitCore which is a bitcoin fork with SegWit+10 (or 20) MB blocks and 2 min block time.

there is no end to these forks and you can never prevent it. they just create new useless altcoins, get some traction, sometimes do an airdrop and then slowly die and disappear.

stop spreading lies. nothing remotely like that has happened so far.

what they did was 2 things:
- ban ICOs which are already either illegal or frowned upon in other countries
- close exchanges which have been working illegally.
