That doesn't really mean anything.  Look at the main page to compare against other coins: http://bitinfocharts.com/

A lot of the big wallets are exchanges, and since BlackCoin is more actively traded than most of the other coins, a lot of money is in the big exchange wallets.  According to the bitinfocharts page, the top 100 BC addresses are 61%, while DRK is at 64%.  Even litecoin, which has existed for almost 3 years and has the second largest market cap has 50% of it's money in the top 100 addresses.

In other words, you can't really draw much of value from this information.

Any early miner who doesn't plan on being a long-term holder has already sold their coins long ago.  The recent spike in price turned out to be an artificial jump/pump and dump effort, so we shouldn't be concerned about the return 30-33k satoshi.

In fact, if we try to prevent the price from falling back down while the coins are dumped, we'd actually be letting the pump and dumpers cash out with a profit for their efforts.  Let them throw away their coins at a loss, or pick them up when they're given away for cheap.

If we want the price to increase, we need to get the word out about all the great things that are happening with the coin.  Not just to our own community, but outside of it as well.  This will probably be a bit easier to do when all the projects planned start moving from the development stages to completion.

We could get to $20/coin if Bitcoin is trading at $2000+ and we overtook the spot of Litecoin as the coin with the second largest marketcap.  That's probably quite an optimistic projection, but it's possible.  At its peak, litecoin had about 9% of Bitcoin's marketcap.  For a $20 BlackCoin at the time Bitcoin is worth $2000, we would need 5.7% of Bitcoin's market cap.  If Bitcoin goes even higher, obviously we would only need a smaller percentage.

This is all amazing news, and several of these factors could individually have a huge impact on price - let alone all of them combined.  But I think a lot of people outside the BlackCoin community don't know about it yet, and many who do are already very invested in the coin.  The price movement is definitely due to 1 or 2 large buyers, and they very well could be real investors - I would definitely have bought a lot more myself if I had more coins around to do so.

Yeah, I've failed today as well.  It's difficult to predict the market when it's one or two rich players moving it.  I only trade with a fraction of my coins though, so as long as the market stays up, I can't complain.

The tough thing to tell with these big buyers is whether they're honest investors or if it's a pump/dump attempt.  While I think the coin is very undervalued, there isn't really a good reason for the price to be moving now.

I don't believe the point of this attempted attack is to lower the difficulty, but to have more coin age than the rest of the network (due to the fact that very little coin age is lost with staking blocks).  So, if the attacker continues to hold more than 50% of the coin age as he mines blocks, the difficulty would actually increase.  However, there may be other factors taken into consideration that would prevent this, and for PPC in particular the 3 month maximum coin age would severely limit the attack.

You're missing the point of what I said.  Since you can't divide into less than one coin, that limits your ability to leverage this attack vector.  So the point is you can't just assume you'll have enough leverage for an attack, since there's a hard limit.


...To prevent attacks like the one you're suggesting (and others).  I am referring to coin age spent on staking blocks, not coin age held in wallets.  Using only coin age spent would obviously be a bad idea as well, so I'm guessing it's some combination of block length and coin age spent taken into consideration, but I don't know specifically what is used in PPC or BC.


I'm not sure what you're even talking about here.  Of course each coin doesn't pick its own chain, the wallet will use the protocol's rules in determining which chain to follow, simple as that.  I think most coins use something different than the simple "longest chain" these days though, even bitcoin factors in work completed.

You can't assume the minimum would be adequate.  You may need to subdivide into millions of separate transactions to provide enough leverage for this to work.  And then whether it will work depends on the specific implementation of proof of stake you're talking about.

I've heard that in peer coin that the coin age consumed plays a role in determining the preferred chain the network will follow, which may make this attack ineffective (if that's staking coin age, since you would consume very little in your attacking chain with this method), but I'm not sure on the specifics.  Someone who knows the details on the code would have to weigh in.  Since most PoS coins are forked from Peercoin, this attack may not be an issue.

There's also a "PoS 2.0" that's supposed to be coming out in a while for BlackCoin that addresses some PoS security issues, but not sure in particular what those issues are.  Might be more info coming out later.

What's the purpose of the minimum global hash rate to earn tickets?  If the ASIC is going to be given away anyway, I don't see a reason to reduce incentive for miners on some days.  Plus, we'd be rewarding the most loyal miners who have stuck with the pool through its growing pains.  (And it's not like a random miner can magically add on 2 GH/s to help meet the global minimum, most miners are already using their whole capacity on the pool if they're mining on it.)

Go here:

mintpal.com/market/BC/BTC

That's the exchange page for BlackCoin on Mintpal.  You can see on the left side are the sell orders people have put in, and on the right side are the buy orders.  Anyone can put in any order they want.  So at the very beginning, the order book will be blank, then people will start to place their buy and sell orders.  When a buy and sell order hit the same price (or overlap), a trade is made (at the price of the one that was already on the page).

The withdrawal fee isn't a %, it's .02 BlackCoins.  While technically it's money lost through no fault of your own, that's like a quarter of a cent in USD.

What's happening is that the orderbook is repeating buy and sell orders repeatedly, so the numbers keep rising.  It might just be a display issue, but can anyone confirm this?  (Wonder if Mintpal has realized this is going on yet)

Be yourself with libertycoin... hell, on Bitcointalk, you can be 4, 5, even 6 selves.

Price up 50% in an hour at 4 AM in the U.S. on a coin that's been trading on low volume?

If your pump and dump warning system isn't going off, it's broken.

It would be good if the locked thread had some links to this one (ideally at both beginning and end) so people who find the thread by searching aren't confused.

Yeah, I have to agree that these guys have done a lot for the coin, I don't know where they've pulled the money out of for some of the promos (30k blackcoin giveaway for the multipool announced when the price was like 50k satoshi i think, free knc miner, $15k to enlist a PR firm).  And that says nothing of time I'm sure many of them have put in.

You don't necessarily have to agree with everything they do, and you don't have to donate to anything they do.  If anyone has their own initiatives and projects for the coin, they are more than welcome to start them or even see if the community is willing to lend a hand.  With decentralized cryptocurrencies, nothing is ever truly official - once it's released into the wild, it's fair game for anyone.  However, the dev team is "official" in the sense that they've been been central to building the coin and the community - without such dedicated people, you end up with stagnant coins that don't go anywhere.  So I'm happy we've got people working to build up the coin, both within the "dev team" and without (though I wish people would quit suggesting "pumping"/market manipulation).

Looks like someone's going for it again, but might be short-lived.

Managed to pick up some free aur in the craziness (bought some cheap, sold a few to get the bitcoins back), just gonna hold for now.

Settle down, it's a joke.  NXT, promises something big will shake the market with the introduction of "colored coins."  Then BlackCoin, a different sort of "colored coin" is the one to really come in and shake up the market.

Looks like someone was trying to bring down the market, but just ended up having someone snap up their 60 btc sell wall @ around 37k


Yep, and I think they failed pretty badly.
