Sounds great!  And which ones are those, again...?  

The problem is, we don't think a coin has profit potential until it has, you know, made a profit.

It will be interesting to see what Coinbase will do next and how circumspect they will be after this crazy BCH rollout.  They did make it very clear that they were going to add support for BCH back in August, but they did also say that the support would happen after the first of the year, so this early rollout took everyone by surprise.  I wonder if it is inevitable that, whichever coin or coins they support next, we'll have the same craziness and price swings.

Totally agree, a true hodler probably shouldn't be too focused on the day to day or hour to hour fluctuations...mostly it just causes anxiety and self doubt.  Of course, enough of a drop looks like a buying opportunity to a true hodler...

There does seem to be a very strong correlation between Bitcoin price up and Bitcoin Cash down and vice versa.  The launch of Coinbase's BCH handling capability has caused it to shoot up, with the accompanying drop in BTC.  I believe long term they should both be owned.

Anyone can make a prediction, and those predictions are just as valuable as what you've paid for them.  We've seen a large dip today, that is a fact.  We have past performance, that is a fact.  The best advice is to have some fiat ready for the next dip and buy in in the short time that these dips usually last.  From 11,000 to 9,000 qualifies as a large dip, and these fluctuations are buying opportunities for those who can move quickly and take advantage.

It's only in the very short term that people can look at the price movement and get nervous, in any longer term chart the uptrend is amazing.  I think people are just so used to assets that fluctuate a few percentage points a month or a year, that when one comes along that can and does fluctuate that much in a few minutes and even more in a few hours, it's very tough for them to keep those swings in perspective.  Some say it's best for long term investors in any asset to ignore the very short term moves, which of course is impossible with Bitcoin because it's just so damn fun to watch the rollercoaster, especially if it's swinging up.

That's a great question, once fully mined and the 21 million attained, if inflation is not somehow eradicated and some other alt(s) haven't taken over the day-to-day transaction workload, I don't see how it couldn't continue to increase in buying power.  This upper limit of coins is such an amazing concept compared to our world-wide acceptance of inflation and ever-increasing money supply.  Then when we're all 200 years old, we'll only be talking about Satoshis...one full Bitcoin???  Come on, who ever could even conceive of that...

That's true, I'm just hoping for semi-endless growth...

I think these are very good points being made, but I would also just add this--ultimately, what difference does it make what, precisely, drove the market so high so quickly, and what, precisely, drove it back down?  No one here has any control or influence over these moves.  In a way, it's kind of like speculating about how many angels can fit on the head of a pin.  It might be wise to take a broader outlook, namely, we DO have past performance to look at, we DO know that Bitcoin has always been volatile and most probably will continue to be so in the forseeable future.  It's something we can accept and perhaps even profit from.

It's interesting to see just how dramatically and quickly these moves can happen.  It really does seem like all it takes is a few whales to take some significant profits, and then it immediately becomes falling dominos, people who were quite comfortable just holding and letting it ride suddenly start thinking, "This could come down a few thousand, it's time to lock in some large profits and let it come down and buy back in later".  And of course, multiply that mentality by several hundred thousand people and you have a "flash crash", a self-fulfilling prophecy.  How fast one can get in and get out becomes an important consideration.  I'm not a trader so I'll just wait and if it does come down a LOT I'll will be very excited to buy more.

These things are frustrating, but you just have to take it in stride, there will always be influences positive and negative in the moment.  I think sometimes we create a lot of our own anxiety, like we not only follow the news but internalize every little move and bit of news.  I read lots of articles pro and con about Segwit2x, and some of them seemed very dire and worrysome.  But Bitcoin remains resilient.

It's always problematic to speculate what will happen in the short term, like in the next few days or even few weeks.  But one thing we do have to go on is past performance, and that certainly indicates that despite the regular challenges and hand-wringing over various scenarios, the trend is solidly up over a longer term.

I don't want to sound mercenary, but ultimately, if you're looking for investment potential, what difference does it make as far as what exactly is making the price move?  If it's a fundamental catalyst, if it's a technical (human trading behavior) cause, or if it's a small group of wealthy whales moving the price, if you own Bitcoin and something moves its price dramatically higher, whatever the mover is, you are benefitting from the ride.

If you currently believe in its potential, it cannot be too late.

Ok, Bitcoin is volatile, everyone here knows and understands this.  This volatility is a separate issue from whether one ultimately believes in it or not.  It has simply proven to be so amazingly resilient that I cannot imagine people just dumping on some news that some people consider bad.  I would love to see it go below 5k so I could add a decent amount more.   

I think it's clearly desirable to own both, but if you're looking primarily for safety and stability, buy gold, but if you're looking for investment potential, buy Bitcoin.  Bitcoin's potential is practically unlimited, whereas gold reached about $1,920 five years ago and has more or less languished ever since.  It's comparatively low right now, so it might be a good time to add some to your holdings, but Bitcoin still owns the "moonish" potential.

I may be optimistic or naïve, but this explanation for the cancellation I find very uplifting.  It seems like people who care about Bitcoin's long-term success and adoption and positive future have put that commitment ahead of pride or intransigence.  I keep being surprised and impressed by this wonderful thing called Bitcoin and so many diligent, hard-working, creative and selfless individuals who remain committed to its bright future.

As of now it appears that there is a very tenuous connection between Bitcoin's price and its volatility.  Whether Bitcoin is $600 or $60,000, as long as it is perceived by most people who are interested in it as volatile, it will retain it's volatility.  In other words, volatility is kind of self-fulfilling, because those who believe it's volatile treat it accordingly as an investment.  I think the more important factor will be much greater day-to-day adoption and usage.  Once Bitcoin is being used for millions of transactions every day all over the world, at that point it's volatility will be dramatically diminished.

Bitcoin is not the world's most valuable asset by a wide margin (gold, real estate, stocks, etc.), but it certainly appears to be the world's greatest growth potential asset, which is much, much more important.

That is so true, so many like me wish we had been paying more attention 7-8 years ago.   

A very key and vital component of Bitcoin is that its maximum supply is set at 21 million.  This eliminates the possibility of currency devaluation that accompanies any currency that can continue to be created ad infinitum.  And since it's divisible down to the satoshi, 21 million will be plenty.
