i don't know who this dude you are so excited about is but just because someone made a guess and that came true that doesn't make them "good predictors". it is like gambling, you can win a dice roll even on the lowest chance but that  doesn't make you a profit if you win.

regarding this part you should not just look at price numbers but instead you should look at how much they really are changing. percentages are best in this situation.
for example going from $20000 to $10000 is a $10000 drop in other words it is 50% drop.
also going from $400 to $200 is a $200 drop but that is also a 50% drop.
at first look these two may seem very different and you may think the first one is a bigger drop but in fact they both are the same thing.

it is too soon to say anything  in my opinion. a cryptocurrency that is issued by the government is somewhat a strange mixture. because one of the factors that has been making cryptocurrency (imagine bitcoin) popular and useful is its decentralized nature. and if a government issues a cryptocurreny it will be centralized and also it may be: closed source and without an open-to-public blockchain.

so it is really hard to say what kind of cryptocurrency they are going to create and depending on what kind, the usefulness of it may be limited and it may not attract any attention and fail.

for now we have to wait and see what happens to the handful of countries that have already done this.

there has been a "whale attack" happening on bitcoin for some time now. but this attack is not taking place the way you think it is. instead it works like this: the whales get bigger each time you let them buy more bitcoin than you or when you sell your coins at the bottom because of panic to them. who do you think places those buy orders at the bottom waiting to fill their big whale bellies

everyone has their own opinions, and you didn't exactly quote a particular person or given any links so we don't know why they said that. you should find it yourself and see the source where that particular person is making that prediction and i am sure they have already explained why they think this year is the last time we are going to see below $10k.

and remember no matter who made that speculation that is still a speculation like any other.

no it is not. there has been no bans anywhere in the world for a very long time now. there has been small prohibitions to certain banks not people using bitcoin and cryptos.
and in India everything is still the same as before.

in other words they have not yet regulated bitcoin but it is still legal to invest in bitcoin and using it.

despite what OP and some of the posters in this topic think, just because price has gone down a certain amount so far it doesn't mean it will continue on reaching your desired price.

and this drop was not any logical drop like a correction or anything like that. this has been a lot of manipulations and FUD going into pushing the price down and this type of drop is never predictable and also never lasts long.

the news about the "investigation" just came out today and a couple of hours ago as far as i can tell from the news websites and that may not have the desired effects that you think it has.
this may actually cause some panic among investors who will then start selling more and postpone the "greed days" even more.

ok, lets take a look.
how many signature campaigs are there? 10? 20? lets say 50 and all of them are spending the same amount $10k per month. that is 50*$10K / 30 = $16,666 lets round that up to an even $20k per day spend on advertisement. and lets multiply that by 2 just to cover any others that i missed and round that up to $50k per day.

total daily trading volume of bitcoin is around $6 to $10 billion per day. that is 120,000-200,000 times more than cost of advertisement.
amount of money transferred using bitcoin per day is about $1-$5 billion which is 20,000-100,000 times more than cost of advertisement.

that is how strong bitcoin is not just some tiny amount going into spam on bitcointalk...

you must be a time traveler from back in 2009-2011ish.
these days in 2018 nobody even thinks bitcoin is remotely close to a Ponzi scheme but you! there is no similarity even. why would you even think that?!

ICO is only good if you (as the developer) want to make some auick money without doing much and then going away to next one.

wrong. it would be worth more only if you advertise it more and pump it initially.
OR
if you are creating a really unique cryptocurrency that can interest people enough to actually buy it because they know it is a useful coin not just another altcoin being added to thousands of already existing coins!

if by this you mean a pre-mined altcoin then your project loses a lot of its value right here...

that is not something that you can control with or without ICO. even bitcoin (which is the biggest of all by a big margin) is not stable.

the only thing i can say is this: Satoshi is a billionaire and he never premined bitcoin and he never ran an ICO. what he did was that he created a useful thing and worked on it to grow it more.

and tried and tried and tried to fight bitcoin, spread FUD about it, talk about banning it, even closing exchanges and all their attempts failed one after another because people wanted to continue using bitcoin and each time the government pushed back, people invested more in bitcoin!
now that they have seen they can not do anything about it, they plan on making the best out of this situation by making some money out of it at least. hence the high tax.

almost every satoshi is unaccounted for. people aren't going to announce that the coins belong to them and they own the private keys! you just see coins (transactions) exist on the blockchain and you have no way of telling whether they have a owner or not. and you have no right to make decisions for these coins. even if they are truly lost.

but the volatility will remain the same no matter what people do. even if they stop hoarding and sell something at the ATH and take profit there and do all the things OP says, price will still remain volatile the same way it has always been.

the problem is not with what people are doing, the problem is because of exchanges! they are too small and hard to trust so they remain small. if you look at order books you can see that a large sell or a large buy can change the price a lot more than it should. and we all know that prices are set on exchanges.
and for that to change we need better trusted exchanges so that people don't feel the need to cash out and never leave an open order. with that the order books will be filled a lot more and the swings become less wild and that will decrease the volatility and we will no longer have 1000% rise followed by 70-80% drops. instead we can have a smooth rise of somewhere around 100-200% rise per year with smaller corrections instead of massive dumps.

not at all.
futures are only limited to a limited number of people from a limited country not the whole world and people aren't all using futures specially because of taxes. but it is hard to accept right now because bitcoin has been in a bear market that we can't shake for nearly as long as futures started.

unfortunately nearly all of these accounts on different social media platforms such as Telegram, Twitter, Facebook and others are scam accounts and groups which were created to fool others and make money from their gullibility.
there is no more legit discussions out there anymore, they hide behind things such as "signal group", "trading discussion", ... and pretend they are doing something useful whereas in reality they are scamming people.

whenever someone is talking about "top traders" and generally call someone "experts" they are in reality talking about some bullshitters on the internet who are self proclaimed experts who are making random guesses about the price. sometimes they come true and they get too excited believing in themselves and other times that they are wrong they blame "manipulation"

i still find this the strangest thing to be created and exist and be used by that many people! (i am trying not to call it dumb move...)

this is a bitcoin vault, and held by a third party! one of the first thing that anyone who enters bitcoin space hears is that you will no longer need any third parties to store, spend, receive money anymore.
all i say is that as long as i can store this
and remember the password used to create it, i have no need of such "vaults" and third parties and the additional risks!

in case you are wondering that is the AES-256 encryption of the private key from wiki with a 16 char long password. for all anyone knows that is just a random text without a meaning but it can contain millions of dollars worth of bitcoin which i and only i can access.

that is true but it will also last a short time. it can not go on like this.
believe it or not at some point in the past the trending saying on the internet was "bitcoin is Ponzi Scheme" and many people believed that. today if you tell this to someone they will most probably laugh at you.
eventually in time when you tell people "bitcoin won't end well" or "is rat poison" they will also laugh at you.

the demand for bitcoin and the buy support is still there and people are buying bitcoin. even whales are currently buying bitcoin that is why each time the dumping stops the price keeps on rising upwards. and that is what you are seeing as today's rise.

but the problem is we don't know if there will be another manipulation and dump or not. the good news is that as price goes lower it becomes harder to do the same thing. so we can't say for sure of this is the start of the rally or not. it may begin now or it may need a bit longer.
