Don't believe in that. Just because he is Harvard professor that doesn't mean he is qualified enough to discuss such aspects of Bitcoin and cryptocurrencies.
I also don't think that Bitcoin regulation does necessary have the negative impact and that will go in the same way like in China. So, don't be afraid and don't believe everything you hear about Bitcoin.

It's not impossibe for China to come back. I beleive the pressure is big and there are many efforts to losen the strict regulations about cryptocurrencies. Since that could be easily turned into great income I think chinese government could reconsider the decision. They have to keep the step with civilized world.

No altcoin will replace Bitcoin and take its number one and dominance. Still that doesn't mean you have to abandon altcoins just have to choose very carefuly which one to invest.
Altcoin market will expand further but altcoins will always stay just the second best.

Bitcoin is already present on different social media, blogs, websites and similar.
But to my opinion there is lack of some serious promotion recgonized by experts and available to people who would take it relevant for geting trusted and reliable information about Bitcoin and other cryptocurrencies.
Today everyone is thinking that knows everything about cryptocurrencies and can teach the others and then we get poor information and people who are mislead.

I don't know any that accepts Bitcoins directly but they were all accepting Bitcoin debit cards and that was very convenient, for all transactions, even very small ones.
The problem is all Visa Bitcoin debit cards were recently suspended, hope just temporary until new provider appears, but that has made quite a confusion.

They could implement some measures to weaken the Bitcoin and to make use harder or even illegal. Also with negative media and social media campaign they could make negative publicity in public.
Still I don't think that is in their best interest and their behaviour will not go in that direction. But the regulation will become more intensive and stronger.

Bitcoin was never supposed to be mainstream currency but alternative to the existing financial service. And it's not the imperative to become exactly like any other fiat currency.
Bitcoin has some disadvantages like transactions fees, confirmation time and backlog, limited number of mined coins but still that doesn't prevent it from being used both as a payment method and investment instrument.

I'm one of affected Bitcoin debit card user and that is a big inconvenience for me.
Still I don't think that this is some special war of Visa against Bitcoin and it will not affect Bitcoin itself in any way.
This is Wave Crest issue, as a Visa Europe provider and I truly hope that Bitcoin debit card service will soon find some new and trusted provider.

This is not possible, not now and not in the near future.
Banks have changed their way of doing business and some changes will still be made but they will continue to exists. The whole world economy is depending on banks as well as governments and cryptocurrencies can't change that.
To believe that Bitcoin will replace banks and make new economy system is just utopia.

I don't expect for Bitcoin to go under 10000$. Never say never but at the moment there are no signs something like this is likely to happen. Some big disturbances might start such big crash but the market is quite resilient now and when dump happens this will be more just correction not the crash.

Many claim that Bitcoin price is and can be manipulated. This somehow makes sense if you think on fact that rather small number of people is holding the majority of Bitcoins and that gives them a space for manipulation.
Still I don't think it's so easy to manipulate the price and that individuals can't influence it without leaving a trace that would be very obvious. That leaves us a question whether Bitcoin is truly independent.

Until the Visa cancelled all Bitcoin debit cards in Europe these days I had no need at all to convert Bitcoin to fiat. I had my coins on the card and could pay with them whatever I want.
Now the situation has changed and it's not so easy the best way to convert Bitcoin to fiat on the most economic way.
I think that this should be the point of Bitcoin that you could easily use it for anything without converting it to fiat.

Exactly, using Bitcoin debit card was very convenient for me, not just for cash withdrawal which I didn't use so often but for paying in stores and for other services just like with any other card. So didn't have any need to sell Bitcoin for fiat looking for trusted sellers or services.
The best was that with Xapo I didn't have to move my coins anywhere or top up the card but when I had coins in wallet they were directly available at the card also.
It's really pitty, hope they will offer new cards very soon.

To own one Bitcoin today is completely different than one year ago for example. It's a small fortune that is not so easy to earn.
My goal for January is to earn enough Bitcoins to make some payments that I have and to start successful saving process with some decent Bitcoin sum saved at the end of the year.

Well, I didn't receive any previous notice except this today. Otherwise I would be prepared and take some actions.
For now it seems that only debit cards related to Master Card are woking, every other related to Visa, no matter the service, is out of use. Not just Xapo cards.
I wonder how long will take until they find a new provider.

If you ask me this is just the begininig of Bitcoin and its true success.
With the price growth the investors profit would rise also, but only for the most skilled ones because Bitcoin market will become more demanding. There is plenty of room for further progress of all cryptocurrencies so this will be exciting era.

I've just received email from Xapo that they were announced by Visa they have to stop card support and all Xapo cards in Europe will be immediately deactivated.
I just can't believe that they haven't received any previous notice and prepare users for that or give some adjustment period. Very unprofessional from Visa.
From this very moment I can't use my card anymore and I'm very angry and disappointed. I know it's not Xapo fault but still they should take immediate action to find new reliable provider.

This chart could only represent some guidelines not something you should stick to and expect the trends will be exactly like this.
Also without update this isn't worth so new values should be filled all the time.
Don't be disappointed when this will not help you to actualy predict the values.

It's all been already said, Trezor and Ledger Nano. Nothing else to recommend.
Still I would suggest to combine the wallets, use multiple kinds, like mobile wallets too, but avoide online wallets, especialy blockchain. And never keep all your coins at just one place.
No matter how wallet is secure always something can happen and there is also human factor that shouldn't be forgotten so additionaly security is never too much.

I don't think so. Every time something become successful and some can't stand it or explain it, conspiracy theory appear. But it's not everything connected to illuminati, although people would like to think so.
Theories like this always attract attention and actualy make publicity for Bitcoin which is not bad at the end.
