Can't see any reason why holding Bitcoin would be greedy. In some way maybe selfish but not greedy.
Having in mind how Bitcoin price is rising just holding can make you profit with literaly doing nothing. And you have some savings also.
Still I beleive Bitcoin is not made just to hold but to be actively used either as investment or payment method and it's good to circulate.

The advice would be never to use exchangers as wallets. Keep there just the amount of coins that you need for trading and for keeping coins use one of the trusted and user friendly wallet. When choosing wallets stay out from online wallets like blockchain, they have the worst security features and your coins could be exposed. And use multiple wallets, don't keep all funds at just one place.
Combine hard wallet like Trezor and maybe some mobile wallet like Mycelium.

I think that times when banks had fear of Bitcoin are over. They look at it as competition but also as opportunity to make money for themselves and offer new services to their clients.
I don't think we would wait for long for the day when banks would offer to their clients to open Bitcoin wallets, savings and similar. Banks are aware they can't stay behind.

When I was realy young Bitcoin didn't exist and opportunities to make some money besides some classic jobs were not very broad. Today is different and Bitcoin is great opportunity for young people to make their own money, to learn about new technologies, financial markets and to develope their business spirit. Some of them who are realy capable have the opportunity to gain financial independence at early age. I advise them to use those chances.

Ha, ha, you are very funny. Doubling Bitcoin in two days.  This reminds me on those so called Bitcoin doublers that were popular some time ago.
I beleive no one so far hasn't developed the technique to make 100% profit in such short period of time and besides that is not possible. You can't achieve that by trading and the daily price movement isn't that big to allow such profit. You will have to change your apetite for profit.

Dead again? How many times exactly we have read such stupid announcements this year?
I'm getting tired of such posts and fullish Bitcoin cash promotions, endless complainig on fees etc. And I have very simple solution for such users - if you don't like Bitcoin just stop using it and all your problems will be solved.

Without any doubts I would say buy Bitcoins. But on the second glance that decision depends on how much funds do you have and what is your final goal.
For smaller sum trading you could choose some good altcoins like Ethereum or Litecoin, for biger profit especialy on long term and with larger sums Bitcoin would be the best.
No matter which option you choose don't invest more than you can afford to lose.

I don't think Bitcoin has the power to replace the banks. Banks will survive but because of influence of Bitcoin and other cryptocurrencies they will have to change and modernise their business.
Maybe some traditional bank branches will disappear and will be replaced by online or something but bank as institution will not disappear. At least not in our lifetime. Too much money, regulation and politics are standing behind them and watching their back.

No other coin will take the Bitcoin place, at least not in the near future, and Bitcoin will remain in the number one position. But since so many altcoins appear all the time and the altcoin market is rapidly growing the procentage of market share might change but not for long term, these values will vary. Some altcoins realy don't "live" long on the market so overal nothing can't significantly disturb Bitcoin position.

I'm not that optimistic and at the moment this sounds exaggerated but one year ago the price of 18000$ or 19000$ sounded exaggerated too.
Still these are only predictions, guessing, no any solid ground or proof for that so this might or might not happen.
In all this years spent in Bitcoin I have learned that it's not too good to rely on predictions. Don't beleive everything you read online.

It's like closed circle. The higher the price the biger the demand and vice versa. Everyone wants the opportunity to make profit and they think Bitcoin is ideal for that.
Today there are only few true Bitcoin enthushiasts, majority just want to make money no matter what it takes. If the price falls significantly that will also happen to demand.

At this moment I don't think there is any country in the world where Bitcoin is formaly introduced into economy, fuly regulated and accepted by businesses. That is the first precondition and without it how could it disturb it.
This could happen only in some hidden area because people use Bitcoins and get some profit out of it but in most cases this is not formaly recorded anywhere in economy.
Still, some rules are changing and Bitcoin will long term influence the economy too. In.what way is yet to see.

I can confirm that. Viabtc is to my knowledge only free legit accelerator that is realy working.
The bad side is limited number of transactions and you have time of about 5 minutes on every full hour to load your transactions. But that is only in case when they are crowded with demands, usualy when the whole Bitcoin network is stuck, otherwise you can upload your transaction at any time.
But once you upload your transaction it get's confirmed very fast.

It's very hard to tell if Bitcoin has influence on global market. The reason for that is that Bitcoin is still not fuly recognized, regulated and implemented in global economy. This is now still functioning in some grey area and it's hard to measure the global impact.
It's true that the number of Bitcoin users is increasing but the impact is on the individual level, those persons influence their own finances or businesses but global impact is not possible to measure.

The price is growing very much and that certainly contributes to increased number of users and Bitcoin popularity. People are eager to make money.
The truth is that volatility is also something that is natural part of Bitcoin and that the price can't just rise forever. So, some dump is expected and some people will lose money. But generaly speaking Bitcoin has reached the level when it can't be ruined or vanish from the scene over the night and very easy. So I don't expect any cathastrophic scenario.

Bitcoin is one and the only true, original cryptocurrency. All other here mentioned are just altcoins and compared to them Bitcoin is way superior with value, acceptance and implementation in real life. All this other altcoins that use Bitcoin in their name are just pale copies and they could never achieve what Bitcoin did.

Honestly, I don't trust them and don't havr confidence in them. Somehow I beleive they can't be programed so successfuly to cover all aspects of trading and to react properly in every situation. Successful trader needs his own mind and experiences.
Robots could be maybe used for excercising or for some smaller investments more to play than to trade seriously.

Since I'm actively using Bitcoin as a payment method to cover my living expenses for me personay there is no big difference between real money and Bitcoin except that Bitcoin is only in virtual shape and it's not connected to my bank. Of course from economic and financial point of view there are many differences between Bitcoin and fiat currencies but once when cryptocurrencies become more adopted in society and legaly regulated the position of Bitcoin might change for the better in that sense also.

For Japan that doesn't surprise me, actualy I was expected that to happen even sooner. This is great news for Bitcoin adoption but when I think if I would like to get my paycheck in Bitcoin, I'm not so sure. Bitcoin is very volatile and this could be very tricky. Maybe just some smaller part and the larger one in fiat money. Still I beleive that many companies will follow that example in the future.

Why would people forget about the cryptocurrencies after holidays? That makes no sense to me.
Anyway, now isn't exactly perfect time for buying Bitcoins the price is heading towards 18000$  and more but still if you have some extra funds to invest, go for it. This is not the peak of Bitcoin price and I beleive next year the price could go to 25000$ so it's still not too late to invest, it's just expensive.
