I do not think there is a profound answer to this question.
People could lose interest in bitcoin, that would lead to a price decrease.
Bitcoin could be superseded by a rival.
Or declared illegal by authorites.
When something like that would happen, nobody can say
And even if such a scenario occured, it would remove bitcoin completely. Only decrease the bitcoin community and the bitcoin price.

Bitcoin can spread weth into underdeveloped counties.
People who could never get a bank account can receive bitcoins from relatives.
With those funds they are capable of creating their own businesses and provide for themselves.

Bitcoin has mastered a few challanges in 2017, and that makes me believe in a bright future of it.
Segwit will activate soon, the fork has passed with nearly no damage, and the mainstream news about bitcoin have turned into neutral, sometimes even positive.
I think we are on a good path to see bitcoin prosper in the coming time.
Not only in 2017, I mean in the coming years.

The reason why I do not invest more in bitcoin is, that there is a bigger chance to lose everything.
It's not only that the price of bitcoin could decrease.
There is as well the chance that one of my wallets gets compromised for some reason.
Or that I lose my keys.
And once the coins are gone, they are gone for good.

Not to me.
A certain amount of money is necessary. It gives me freedom and takes away sorrows.
Too much of it does the opposite. It makes my thoughts circle only around money, cages me in. The real life comes too short.
After all, money is for living.

In my area you would need a large amount of bitcoins to buy real estate.
So no, I would not do that.
To me (and I think to the majority here) it's the case that I buy bitcoin with fiat, and consider that to be my investment.
Reinvesting my coins into something else does not make much sense to me. At least not at the moment.

There are different types of hacking.
If you mean to develope a program that finds the keys to a wallet by a mathematical alogorithm, then I would say hacking a wallet is not possible.
But phishing is another kind of hacking. In that case the human is in the focus.
Finding and collecting patterns in his behaviour (like the passwords he normaly uses) can be managed by programs.
Maybe sometimes that way leads to a successful hack.

Wo-hoooo!!!
I didn't think it would go that quick! But 3K is not the end! Not even close to it!
After the fork and with upcoming segwit, I am convinced we will see some interesting developements even in this year!

I don't think that bitcoin cash is accepted anywhere at the moment.
It's just traded at exchanges. As far as I understand it, bitcoin cash is one of many altcoins
I see better chances for ethereum to surpass bitcoin, but even that scenario is very (very-very) unlikely to me.

In that case, personally I would not invest.
As a student you need your money every day. I think there are better things you can do with your birthday money than investing it. Like enjoying your life, for example.
Besides, there is no guarantee that you end up making profit. And six months is a relatively short period for an investment.
Later, when you have a regular job and 250 pounds are not that much anymore, invest it!
But for a longer term then. And maybe even a larger amount.

I do not think that anymore.
Bitcoin has a very large fanbase. Bitcoin is accepted as payment.
No new cryptocurrency can bring that.
Even if the code would be better, the transactions faster and more secure, I see no way that sufficient amount of people would leave bitcoin to associate with another currency.

Sent bitcoins are gone. There is no way from a technical perspective to return a transaction.
Of course, if you know who the owner of the address you sent your coins to, you would have juridical options.
But that would most likely cost more than the amount you lost.

Bitcoin goes up and down and many people earn from that.
On the long run bitcoin has increased its value a lot, you just have to keep a cool head.
I really think it's good the way it is, smaller and even larger crashes are part of the game.
It's the same with the stock market.

I think its uncertainty and fear that cause many crises.
Put enough of it into the cryptocurrency market, and I am relatively sure we will end up back at 1000 dollars.
That could happen when people do not have the option to exchange their bitcoins into fiat.
Let a few exchanges collaps or be closed by authorities, this would be one possible way I can imagine such a scenario happen.

I think as well that the crypro money we use now is the first wave.
But I am relatively sure as well that a second wave will come. And some features we have today (such as anonymity) will not be part of the second wave.
Still, I am hoping that somehow we will be able to take what we have achieved today in terms of community and acceptance and take it with us into the future.

Of course nothing is sure, but August 1st is not coming as a surprising event.
So I do not expect that the market reacts on it in a dramatic way.
Some minor corrections can happen, but nothing out of the ordinary.

I do not see bitcoin to reach 10K in 2017, and not in 2018 as well.
Those numbers are just too high.
After that, who knows.
For the moment I expect the price to be volatile between 2300$ and 3000$.
I suppose it will swing between those levels for a few months now.

To me the purpose of saving my coins is to have a lot of fun later.
I see a (not so small) chance, that my coins will be worth something in a few years.
The could really boost up my retirement fond. At least that is what I'm hoping on.

I think it's not only the governments that want to track you with cashless money.
I'm sure, the industry would like to do that too!
Of course there is the banking secrecy. But many of the people who work in banks do not really care about that. Especially not if they are paid for information.
Imagine the companies, maybe even your neighbours know all about your finances with one click in the internet.
I would not want that.

I still think that altoins are just for trading. So they are an object of pure speculation, and once speculation is over they will have a big problem.
I do not think that the internet needs more than one payment system for cryptocurrencies.
And that is covered with bitcoin.
Maybe alts have better codes, maybe they are more anonynmous or even will reach a higher market capitalization.
Their problem always will be, that they came too late.
