Talking is easy but not when doing the activity. You say buying when it's down and sell when it's up like some kind of predictable activity but it's actually all wrong. The main problem is when we can sell or buy the specific coin since the price could crazily increase even after you've sold some of them or the price could just drastically dumped even after you buy some of them.
Yeah, Bitcoin is not going to die soon but the problem is that if the price going the opposite of what we've predicted. we lose money. The bitcoin is not going to die, but the traders will have the burden of losing after all.

Glad to see a project that finally provides alternate energy for the world through the decentralised market with blockchain system. It'll sure attract many interests and make the world better. We're now tired of unrenewable energy sources that result in many disadvantages and the awesome project is right here.

Multi-signature escrow would be a great idea for additional security and increase the trusts from the community, however, if the following person has met the requirement of being a good escrow and trustable, there's not going to be a problem. The community itself will make an examination.

Saying bitcoin bank where bitcoin is basically created in order to make the decentralised financial system just doesn't make sense. If the government themselves want to tax the bitcoin users, the users need to make a letter of recognition in regard to their real amount of wealth, of course, there's always exists some possibilities that the target of taxation's real amount of wealth could be faked.
Rest assured that there will be no silly bitcoin bank.

Really normal thing seeing that ATM requires electricity, places, and so on. Basically, ATMs are available just to make the transaction of either converting money to bitcoin or vice versa a lot easier, regardless of the overwhelming high fee which every transaction requires.
Though, If you have a good connection and internet banking, why did you go to the ATM for no reason? just simply go to your local exchanges' website and buy bitcoin there.

These two have (at least) the same function that makes both still comparable. Bitcoin have its feature to send money worldwide, so does with PayPal. and if there's a question such "Will Bitcoin overcome PayPal?", it's basically asking about people's speculation in regard to specific feature with the same function which Paypal and Bitcoin have. It does make sense after all. If you're still saying that these are two different things, it's right, but, you actually don't get the real meaning of the question.

Just my random guess. There's no way someone could make double spend if they're paying for the ticket in the airport, they just have a small amount of time and to do the double spend, there are some requirements need to be done. Otherwise, if online payment is available, the airport themselves could simply enable 1 confirmation as a requirement. Things like double-spend will be solved immediately.
and one more thing, you did never hear any double spend cases because no one is going to leak the cases to the public just for the sake of few dollar or yen.

Leaving the campaign. Thanks

Potential is always there, the movement of a crypto coin is rather unpredictable if you compare with some of the fiats and it's far volatile. The current crash may indicate that bitcoin have its price correction and there are so many chances that the price will be increasing within next week or months.
Did you see how bitcoin's price increasing significantly just within a month time span? Looking from that, bitcoin has the potential that some people may not see.

Regrets or not is relative. It still matters about the time whether bitcoin keeps on holding its value on this amazing price or become obsolete by the time being and replaced by another digital currency.
10-20 years is a long time to go and there's no way to save up in form of bitcoin while most professional out there consider bitcoin as a short-term investment, unlike gold in which price always increasing steadily alongside with the increase of years.

Nah, skill is another factor, the only real factor that determines how long a trade could last is the market itself. The pump and dump are decided by the market. Even if you're kind of skilled trader who always got high profit but if the market is pretty stable and rarely have movements, it seems that your trade will take forever.
And in my opinion, different coin have a different time to pump and dump, most of it uncertain though.

Out of curiosity, how about the confirmation which needs to arrive? Is it just accepting zero-confirmation just like some bitcoin payment gateway do?. The average confirmation needs about 15 minutes to arrive and probably some people still have some time to wait for it until the plane's landing, but, how if the fee is just not enough and the transaction get stuck?.

The thing is that freebies often don't last long because basically human's nature always wants something for free and therefore so many people are hunting these freebies which result to mass claiming and the stuff just gone.
And the traffic which comes from this keywords often don't have qualities, most of them use VPN and come from third world country. The people from first world country don't give a shit because they could just spend their money on this stuff because it's practically cheap or simply hire people to claim.

But may affect the regulations or acceptance of government towards bitcoin but well it's fine, as long as the price keeps on increasing there's nothing to worry supposedly until further information from the local governments of whether they will accept or refuse, it'll then affect the price of bitcoin, only if the government is the one which rule developed country though.

Actually a bit worried of price correction, it may occur and the price will be dumped so hard or else it'll never happen, actually pretty disappointed of this price increase because currently saving up my money in form of altcoin and all of these have affected by the price increase, and the result, price dump.
Predicting the price of bitcoin is just now becoming nonsense because bitcoin has proven itself to increase from $1000 - $2100 within a short amount of time, a few years ago, people say that it's stupid to say that bitcoin will eventually reach above $1500 but now it really makes sense.

There's no obvious fact of whether the price will increase or decrease, the information which you obtain from your analyzation itself is actually exists to help you make your guessing so it can be called educated guessing supposedly.
And keep in mind that sometimes an information could get you wrong, something there's an information popping out telling that it's a sign of price pumping but thing happens the opposite, It's from my very own perspective based on my experience. Though people may find it out different so it's up to whom to consider.

ETH just not yet facing the scalability issue just like bitcoin so it'll eventually as slow as bitcoin when many people use it and the amount of transaction going on the increase as much as bitcoin, alongside with the fee, just like what you mentioned.
And also, most of the exchanges require many confirmations if from ETH's blockchain and it's also something to be thinking about.

The price is not the right factor of why people are attracted to use or invest in bitcoin but its volatility, the price just overwhelmingly reached an unusual state of 2000 USD within a year and it's really a good thing especially for those who seek good investment for a short term. Any other investment such as property or gold are steadily increasing but slow, if someone wants to grow their wealth within the short time span, bitcoin is the right choice and that's why people get attracted.

Don't you think that technology always growing so fast that the internet is now almost reached every corner of a developed country? It's really possible that in the future we'll all across this world have a good internet connection and the use of bitcoin for daily life will be very possible.
The conventional money will fade alongside with the growth of educated people, they'll know exactly why conventional money is not effective anymore. We'll soon come to a digital world where everything will be done digitally to increase the security and safety.

That's why bitcoin often be said that it's a short term investment which volatility far surpasses gold. Gold as investment having a stable price and steadily increasing by the time, it's like a property, always increase and rarely decrease. But, bitcoin is a different thing, the volatility behaviour of bitcoin make traders could earn as much profit within the short term of time but also high risk. For people who don't want to suffer from always monitoring the current price of their investment, bitcoin is a disaster.
