1  Economy / Speculation / Bitcoin broke $12,000. Still a good time to buy imo. on: January 28, 2018, 07:39:05 AM
Bitcoin has just broken $12000 on coinmarketcap. That level has been the primary resistance for around 1 week right now. Whenever the price has came close to $12k(high $11k's) the price has dropped to under $11k.



What we consolidate from the above chart is

1. Bitcoin price is slowly stabilizing from the fall.
2. $10k support is very strong, if bitcoin heads that way then it'll naturally go up as a result to pre-correction levels.
3. A move seems likely soon, either way. The price shouldn't stay within this thin bracket of $10-12k for long.

I personally think that it's a great time to buy bitcoin, because considering all of these facts, the worst that is going to happen for this and next month is bitcoin going down to a little over or around $10k and no upward momentum builds up. You would be taking a 17-20% loss if that happens.

If bitcoin does break out, however, then we shall be looking at $14k as a short term target, potentially $15k. After that though we could be looking at getting to $20k finally.

What we will have to see over the next few days is that whether this $12k level can stand the test of time. If $12k's resistance becomes support, then $15k per BTC is just a matter of time.
2  Economy / Trading Discussion / Anywhere to trade on 1st August? on: July 31, 2017, 10:19:53 AM
As we all know most exchanges will be closing all their trading activity in preparation of the 1st August event.

Is there any site on which you can still trade with existing balance(note existing balance, of course i don't expect to be able to deposit on that day) for altcoins as well as fiat $$$? If there are any, please let me know because i would like to trade on the day when it happens.

And also anyone else being bombarded with emails saying what will happen to user funds on 1st August from bitcoin accepting merchants? Grin

Thank you all!
3  Economy / Trading Discussion / Is it safe to sell bitcoin for paypal like this? on: July 05, 2017, 12:29:34 AM
I have a question for all experienced bitcoin traders out there.

If you want to sell your bitcoin for paypal, can you ask someone to send as friends and family and the chargeback, and close the dispute so that they can neither open a dispute for item not as described nor as unauthorised transaction?

It makes sense becasue you're not allowed to dispute further after you open a dispute of that category, correct?

Thanks all for the help.
4  Alternate cryptocurrencies / Altcoin Discussion / XC uses multisig address and transaction? The answer is NO!! Look at facts here! on: August 16, 2014, 06:40:45 PM
OK, since there are too many fuds on the old thread, I decided to close it and open a self-mod one.
===
XC, a hot alt coin, claims that it is a trustless system and uses multisig technology to do it. See below



But I am puzzled by the fact that despite they talk like this, I don't see a single multisig address in XC nor do I see any multisig tx. As we all know, these are the central parts, if we do use this technology, we will see a lot talk about it, like in whitepaper, in thread discussions, the multisig addresses and tx are shown in the blockchain explorer etc (look at Superoicn/MammothCoin's threads, there are plenty talk on that. I can find quickly 10 multisig addresses and associated with transactions, they are currently doing alpha tests in mammothcoin network, so all the multisig addresses are for Mammothcoin, soon I expect to see for supercoinsm which is scheduled for beta tests). Can anyone show me XC's multisig addresses and their associated transactions?

This should be an easy thing to do. But since I don't see any, I doubt if the multisig is really implemented in XC. It looks more like a scam to me. Also, when I search the XC thread, I see this from someone (likely a dev of XC):



m-of-m multisig? Are you drunk? What fun will you have to have m-of-m multisig?? If one guy is bad then you want the wallet is locked forever? Do you guys understand what is a multisig address and how to use it?

It looks like this is a scam. Otherwise please show me some good examples you use in XC.

BTW, for Mammothcoin, they are testing for multisig trustless systems now, you see plenty multisig addresses and transactions there, you can even join the tests I think. There are some recordings in Mammothcoin/Supercoin's thread, for example:
http://screencast-o-matic.com/watch/c2j2IinsMO

and this is one of many multisig address with some transactions associated with it (there are plenty similar ones):
http://chainz.cryptoid.info/mamm/address.dws?bTz39geL1BR5UUdAciB8oh1F33eW1FXFcW.htm

Also they explained very clearly the concept and detailed workflow they use for the multisig trustless system:
https://bitcointalk.org/index.php?topic=736705.msg8324932#msg8324932

Can you show me similar details in XC? If it is really there Grin

EDIT: The answer seems no, the XC dev provided two links with only regular XC addresses. People in the forum created examples of the XC multisig addresses for them  Grin See below:

OK, for those from XC who never seen a real XC multisig address, let me show you what it is, and you can tell me if there are any exist today on the blockchain Grin

All the one posted in the above links by synechist are regular XC addresses, they are not multisig addresses, why? because XC's multisig address starts with 4, not X.

I downloaded XC wallet, and from there in console, I created 2 multisig addresses.

I used these 3 private-public key pairs:

public key: 033942099d7fb91a51b0e2899040c36cf5337002f43b2e80ec3afe3c81cbb5a3db
private key: X35fMeU3c159SX4tWVnA7ZW7DxTyw7BCqEmt92Nw5N87kezytJSZ

private key: X2z4smxErHnkVBZnWzfPMDMNdMvD3mAnB7w7YD1BFeppf3iqUyWJ

these pairs are derived from the addresses I have. From there I created 2 addresses: 2-of-3 multisig address and 3-of-3 multisig address (though this one is of no use - just to show):

2-of-3 multisig address: 4ShqMQFoQFLBzhXDs3aJJMnDNLZ9JTrxKH
3-of-3 multisig address: 4XCmiwfQCm6gQNrW6kaXZJawLPekQGQf5o

BTW, you can make some deposits to 2-of-3 multisig address, and I can show you how to spend it. I can do a tutorial for you guys who have no ideas on what is a multisig address. Grin Grin


wow, thanks some138 to show us what are the real multisig addresses in XC.

From what XC's dev's post, and the "multisig" tx and address they provided in the above links, I can say that they did not understand what is a multisig, they mixed multi input/out tx with multisig? Anyway, they did not seem to implement the multisig at all. Looks like they've been cheating all the way along (consciously or unconsciously).

Multisig addresses usually start with a different letter than their regular address. For example, Bitcoin's regular address starts with "1", its multisig address starts with "3". Supercoin's regular address starts with "S", its multisig address starts with "C". Mammothcoin's regular address starts with "M", its multisig address starts with "b". etc. For XC, its regular address starts with X and multisig address starts with "4". Everyone can create a multisig address using XC client and verify yourself.


I will re-post some key posts from last thread here.

Also let me post the simple question here (will take 30 sec if you go to Mammothcoin or Supercoin for the same question):

provide us an XC multisig address that has tx associated with it, in the blockchain, so we can inspect and see what is there. This can prove you actually have the capability of multisig.

EDIT: now XC acknowledged that they don't use multisig, this has been our doubts all the way along, now confirmed by them.
