Remember that bitcoin is just money. So you are really asking "What do I do with money?"

well... Spend, save, invest, donate, ...  Whatever you want to do. Bitcoin is actually your money and you can spend it around the world. No one can keep you from spending it or compel you to spend.

I think bitcoin is money and like any money it actually is not worth much at all. You can't eat it or live in it, etc. But money can be valuable as a store of value if it has certain properties:

1. Can't be cost effectively counterfeited.   
2. Is believed to have value.
3. Is exchangeable in fungible units.

If these factors change, that would greatly impact valuation.  Beyond that bitcoin has additional properties of privacy, speed, and cost savings. One can see that as the mem pool backs up or larger fees are required, the utility is degraded a bit and so is interest. An open and free bitcoin network also depends on net-neutrality. A loss of that would be very destructive to the utility and value of bitcoin as it would allow any ISP, government, ect. to add whatever fees or restrictions they want.  Fees that go beyond the cost of mining.

On a week to week basis the main factors are supply/demand. The current spike in price is mostly just an increase in demand in Asia. Of course when speculators see a demand increase they jump in and drive the price higher. This ends in a correction and we start all over again. 

I just ran it after reading this thread. Unfortunately I didn't really see the growth that was mentioned.

Can you just send me the doubled coins first? Since you have Harry Potter doubling magic, I'll thank you in advance.

A good choice? Are you kidding me? No, gambling is a strategy for the hopeful fool.

If you want to make money gambling then buy a casino, the house does not lose. They are very likely to win any bet placed. The patron (a.k.a. the mark) is very likely to lose any bet placed.

Some guy said something!!!! OMG, this must be huge!!!? 
 

lol, you may be right. Don't worry though, I do not trade on "feelings". I trade only on mathematics. But a crash? Man that was barely a fender bender. 

Never.  I spend the best money there is. I don't want your state monopoly money. Thanks anyway.

Nope. So much so that I recognize what a stupid idea gambling is. But I think superstition rules in many markets. In fact it is how I make my money in markets. Look for blind trust, unfounded beliefs, etc. Then bet against them.
 

An alt-coin from a totalitarian dictatorship. Sounds legit. 

There is no question. DAESH is known to have used BTC. But there are very few in the "caliphate" who would know how. They have there own currency anyway. Apparently they are gold bugs.


DAESH Coins in gold, silver, and cooper.

Does this really need to be asked? Can money just "double"? Of course not.  

EDIT: Ask yourself this question. If they can double coins, then why do they need me?

To be clear. The Tx fee is in no way a "tax". Taxes are issued by governments, not math equations running on a distributed network.

Is this the "crash"? Meh, come on we can do better than that. My gut says $1800.

That must mean that you are a productive member of the bitcoin economy! Unfortunately most users are just speculating. A speculation based economy is going to be a roller coaster.

IMO, it is never a good idea to buy alts. For bitcoin I look for a bubble then keep a bid about 25% lower. Then I hope.

You are not actually expecting an answer right? It is about as productive as asking what tomorrows winning lotto numbers will be.

I see that all the time also. But when I call and they hand me over to the right person they are able to do it. I think a lot of places start taking BTC but do no employee training. Since they likely only see a few sales it is a novelty when it happens. Hopefully people will start spending bitcoin and then we really explode. The growth we have seen is trivial compared to retail adoption.

Except that the trades are Euros, dollars, and Yen. China lost it's seat as the center of gravity in the last two months. However a big sell-off in China would still send markets down, so I am hopeful for a correction down to -$2k levels. That would be buy sign to me. I could even imagine a $1700-$1600 range crash.

Fund your accounts. If it happens it may not last long!

This link leads to many threads about how to do a paper wallet. It may be different depending on the wallet you use.

The most important thing is to think in terms of theory. In bitcoin there are public keys for receiving payment and private keys for spending. If you do not have complete, exclusive control of your private keys then you simply do not have bitcoin, IMO.

Online wallets typically are running a wallet for you. Of course if they are hacked, or dishonest, or get wiped out in a tornado then your money is gone with no hope of recovery. In bitcoin you must do all the work. You are the CEO, the security team, etc. There is nobody superior to your authority. So be careful.

What I do is store most bitcoin offline in cold storage in a bank vault (banks are still good for some things). I also keep a small amount on my phone using an online wallet system. Even though that money is more vulnerable, it is so convenient that it is worth the risk to me.
You may want to develop your own policy, but if at all possible... trust no one.
