to match $14 dollars, you will need a scrypt rig that can mine at around 4.7mhz. If you're looking to purchase one TODAY, then SHA256 seems to be a better option as you can get the ANTMINER S1 on ebay for $500-600   A scrypt rig will cost alot more than that  

Even with the difference in power usage?

I did not calculate power usage. It was base purely on mining power. If you take power usage into consideration then you'll end up paying more for a scrypt gig, thus your profit will be lower.

I can see that the price differnce is pretty large at 3000 for the scrypt miner but the power for that scrypt would be about 98w compared to 350-450 with the ant

98w? typo?

[mikenz]

Hi,

I bought in Blackcoin a few days ago and transferred all coins in my wallet. Im absolutly convinced by the concept, however, can someone answer my POS-related noob-questions?

1. If all Coins are mined already, where do the 1% stake-coins come from?
2. Why does the staking only works when I have my wallet open? shouldnt the calculation be executed by the blockchain??Is the staking executed by the client or by the blockchain?



thx guys

98w? typo?

Gridseed chips are very powerefficient when it comes to scrypt. ~7-10w per 5-chip unit, so around 100w for 10 of them.

I just started mining on the multipool today, and I'm not seeing much. I realize it's in beta, but how long roughly do "shifts" go? I've been getting shares for the past 6-7 hours and still no info other than shares. When will I see results?

[Ziploc]

why can't the wallet have an option to only be unlocked for staking but not allow for any transactions to be SENT? then ppl could leave their wallets unlocked to stake without worry of being stolen.

Good point we will try ask rar4 for that feature.Something like transaction password block

That is already in there. I have mine unlocked and can't send transactions without entering my pass.

Check again people. I just did, and not for the first time. No password is required to send from an unlocked wallet. And yes, I'm using the latest release (windows client). I brought this up weeks ago in a cautionary post, before Soepkip had his coins swiped, and then subsequently. For the future health of the coin and anyone owning it, let's tie up this loose end.

Just to follow up with a couple more details and confirmations on this.

1. If you unlock the 'new' way, via the <settings> dropdown, you're wallet is up for grabs. No password is needed to send out your coins.
2. If you unlock it old-school, via console, you will unlock for staking. It is a 'mintonly' command, fortunately. Thank god someone was thinking.
3. If you do #2, then initiate a send but cancel out before entering password, your wallet 'lock' symbol will close, but your staking light remains 'green' and mouse-hover will indicate you are staking.
4. If you do #1, then go back to the console and enter the command 'walletlock', same result as #3. (as someone else rightly pointed out).
5. Only remaining question is, for #3 and #4, is the wallet in fact still staking as indicated? I am waiting to find out. So far apparently not. But we shall see.

Conclusion: if you just do #1 and walk away for the day, you might have a very nasty surprise waiting for you when you get home. Even if no one has physical access to your computer, it can occur through a variety of exploits that someone gains remote access to your system. Then, my friend, you are most certainly fucked. Finally, if you don't already, consider using a password mgr. Among other things it will allow you to enter your long-and-random-as-fuck password without entering keystrokes. And be sure to keep a backup of your password database!

if You do no 2...the stacking works...just received few fractions of coins

Well yes, it's supposed to work that way and does. You will also be staking by doing #1. The open question was more about #3 and #4. So far it looks like client is misreporting, and in fact at that point you are locked and not staking, in spite of the green light. Not a major issue. Security is. Looks like you're ok with #2. No doubt future releases will add features and heightened security.
Be sure when you unlock in console to immediately delete history.
**footnote for experts: there is always a possibility that, in spite of deleting console history your password is retained somewhere in memory and retrievable by someone clever enough to get in. It's beyond my skills to verify that, but would be glad to hear a report from someone capable of analyzing the matter in detail.

actually no2 might be dangerous also.....just checked and my transaction passed without password......

I then did walletlock command.....
wallet is locked now and the stacking icon is green...will have to check if it is really stacking....I came to the same questions as yours...will try to report if I will get something...

Strange. I confirmed earlier that #2 demanded my password. What client are you on? Could you restart and reconfirm please. I'm on the latest windows qt.

v 1.0.5

just retested the no 2 and worked as You described......however before I was staking for some time and I don't know why it didn't asked me for a pass...

had no idea you're talking about about gridseed, thought it was just GPUs. LOLz


payout on the multipool is one per 24hr

I have an honest question.

To an investor in wall street how can i explain in a single powerpoint slide why Blackcoin has bigger Market Cap than Mintcoin, they have same features. Mint was released 10 days before and is hybrid POW/POS, to an outsider they are practicaly the same

Im conducting investing rounds, i now FAST/POS is the future and i need your side of the story, for an possible investment.

Thanks.

All coins are not mined already.  Mining still happens, it just doesn't use PoW, it uses PoS.  You can still "find" blocks but it is based on your stake, rather than hash power.  

When your wallet is open, it is effectively doing PoS, and trying to find blocks.. which generates the 1% coins, and confirms transactions.  The whole concept is still 99% bitcoin, except it replaces PoW with PoS for finding blocks/confirming transactions.

[ssaCEO]

It is great you accepted BlackCoin at your casino, but do not pretend like you are bringing extra value to the community. The only one benefiting from you accepting BlackCoin at your casino is you, so please stop acting as if you are doing the BlackCoin community a favor.

I take exception with this. It's obviously of value to BlackCoin to have merchants and gaming sites start accepting it.  I never said I was doing anyone a favor, obviously we're in business to make money. We didn't start taking BC because we're doing charity work, we started because we've been looking to diversify out of Bitcoin for some time, and think that BC has the best combination of qualities to make it a viable long-term bet for us as a new market and store of value.

As far as our Alexa rank, sure we are relatively low traffic compared with the BTC casinos that accept American players, and players in other countries where online gambling is illegal. We block anywhere up to 85% of our hits. We don't think it's worth the risk. But isn't it better to have a casino in BC that's acting legally as opposed to some site that's violating US and other laws? I think it's clearly a benefit to the community in that it adds legitimacy and gives people something to do with their coins besides just trade them back and forth for BTC.

In any event, likewise, best of luck with your project. If you succeed, I'll be the first in line to get one of those cards. I really will.

1. Mintcoin is pre-mined by the developer. Roughly 3% of the total money supply he gave to himself. The crypto community tends not to like such schemes.
2. Mintcoin dev launched the coin saying the pre-mined coins would be spent on bounties etc but weeks later he refuses to list what he spent the coins on.
3. Mintcoin has 20% rate of interest compared with Blackcoin 1% rate of interest. The higher the rate of interest the great the dampening/suppressive effect it has on price as some of those new coins will get dumped on the market.
4. Blackcoin has a great developer. He's responded very quickly to any issues that have arisen.
5. The community has pioneered innovative concepts eg the blackconimultipool, a pool to boost blackcoin price whilst decrease the price of competing alt coins. Encouraging for the future.
6. Community and trading volume. Mintcoin trading volume is tiny. Very few people are buying and selling it on exchanges which suggests to me a lot of the activity in the mintcoin community is sockpuppets (one person with multiple accounts).

Those are specific reasons. There's lots of general reasons why two clones with identical features (seemingly) have different values. Feathercoin is a clone of Litecoin with 4 times as many coins and it has been out for 9 months and is nowhere near Litecoin's price. Community support is a huge factor in a coins success (see dogecoin for example).

1. Mintcoin is pre-mined by the developer. Roughly 3% of the total money supply he gave to himself. The crypto community tends not to like such schemes.
The premined was 1% and is in custody of a Fund, David Latapie runs it- Check.

2. Mintcoin dev launched the coin saying the pre-mined coins would be spent on bounties etc but weeks later he refuses to list what he spent the coins on.
Same answer, the premine is still in power of a NGO Fund, being registred in France. 1%

3. Mintcoin has 20% rate of interest compared with Blackcoin 1% rate of interest. The higher the rate of interest the great the dampening/suppressive effect it has on price as some of those new coins will get dumped on the market.
Well thats an reason for holding long term on Mintcoin (im conducting long 2 years investment rounds on the future of money)

4. Blackcoin has a great developer. He's responded very quickly to any issues that have arisen.
Thats right, also mint great guys.

5. The community has pioneered innovative concepts eg the blackconimultipool, a pool to boost blackcoin price whilst decrease the price of competing alt coins. Encouraging for the future.
Thats something i cannot explain to investor, i will lose them if i try to explain that far complexity that just rebuy coins, and in my perspective ASIC will kill multipools and shitty coins in 3 months. 3 months after first knc Batch

6. Community and trading volume. Mintcoin trading volume is tiny. Very few people are buying and selling it on exchanges which suggests to me a lot of the activity in the mintcoin community is sockpuppets (one person with multiple accounts).
Blackcoin moves a lot, thats true. Mint is more on a low state not much attention on it now.


Besides those are specific reasons. There's lots of general reasons why two clones with identical features (seemingly) have different values. Feathercoin is a clone of Litecoin with 4 times as many coins and it has been out for 9 months and is nowhere near Litecoin's price.

MINT is PoW/PoS hybrid so it doesn't have blackcoin security flaws

+1. Pure PoS is new, which is exciting and has great potential, but its security has also not been as tried and tested. Plus people really need to get over Mintcoins premine. It IS being used to build infrastructure, hence mintcoin is on 23 exchanges and already has 34 merchants accepting it, the Mintcoin Foundation is in the making, other developments surely on the way. We need to find better selling points for BC other than the fact that it has no premine- especially considering the PoW phase was only 1 week long and anybody with any sense of what that means understands that that is essentially an insta-mine. Sorry, I am a supported of both Mint and Blackcoin but I like Mint more in the long term even though I've made more money off of Blackcoin (that should say something).

point #6 from mr_random is a joke. mintcoin is on way more exchanges than blackcoin so of course its volume on any given exchange will be lower. Also, if anything, blackcoin is the one being manipulated by sockpuppets- the community is much smaller and just pay attention to the market and you can see people selling to themselves/buying from themselves (this has been pointed out many times by other people on this thread who also support BC).

Please don't listen to mr_random, there are much more unbiased people on this thread who support BC and will give you more honest answers which don't rely on bashing another coin (I'm not saying listen to me, I have conflicting interests too although I honestly want both mint and bc to succeed and dont see why they cant, but don't listen to mr_random as he has demonstrated many times in the past that he is little more than a shill for BC).

Assuming this is indeed an honest question and not just an intentional ball-toss to Mint-promoters who relentlessly try to fud this thread because they see BC as a direct threat and competitor:

The two coins are very different, most notably in with respect to inflation as has been pointed out. We don't have all the facts about the Mint premine and where it went and probably never will, so I'll leave that aside. As far as 'the security risks', if you read a couple pages back you'll see that I and a couple of other informed people posted regarding Sunny King's rewrite of PoS earlier this year, which resolved the flaw, as confirmed by the person who first identified it and extensive peer-review. At this point that crap is all just FUD, almost invariably from Mint enthusiasts, and is growing tiresome.

Also, just bear in mind that people will tend to talk up the coin they are most heavily invested in. Any idiot should be able to see through that. I will refrain from talking up the 'awesomeness' of BC. Do your own due diligence. Taking a poll on a bitcointalk thread hardly qualifies as research, if that is your sincere intention.

LMAO MINT is pure PoS. Don't you clowns even know about the coin you are shilling? It was pow/pos initially, like Blackcoin was too. But they are now both pure proof of stake.

And lol at anyone who calls me a shill. I've been a member here for a year and have 400+ activity. Unlike a new account created to support Mint.

And as for mint being on more exchanges that strengthens my point. Even with the support of Cryptsy MINT still has a pathetically small trading volume. Some days less than 20 BTC traded on Mintpal for MINT compared to daily 400+ BTC blackcoin days for over a week.

Still waiting for that list on what all the MINT premine was spent on. Blackcoin has no premine and has brought more innovation to the table with the blackcoin multipool that mintcoin has then tried to unsuccessfully rip off.

So funny seeing all the mintcoin bagholders rush into the blackcoin topic to try and spread FUD. How do you think that looks to outsiders viewing this topic?

LMAO MINT is pure PoS.

Mintcoin (code: MINT), also known as MintCoin, is a peer-to-peer cryptocurrency that uses both proof-of-stake (PoS) and proof-of-work (PoW) systems.

https://en.wikipedia.org/wiki/Mintcoin

it's hybrid, so it avoids the known blackcoin security weakness
