C'mon! That's not even remotely bold!

Bold enough to be wrong.

ya i'd like to buy a PUT

100$ strike price 200BTC

how much?

BTC40, send me PM so we lock-in the price and details.

40BTC or about
so that i can sell you 200 BTC for 100$ each anytime before june.
an ok deal if you think bitcoin might go down and want to sell them if they do go down.


i'm going to have to pass i just realize i want MORE  Cheesy

Or you could stay awake from now till june and sell if it looks like it's going down. :-)

ummm... sell when it looks like it's going up to fast, not the other way around :-) Otherwise, you're just being shaken down.

If we do not breach 95, we have a bullish pattern. If we do breach it, then we will go sub-79.

If we do not breach 66, then we are heading up. If we do breach it, then we crash to 50.

If 50 holds, it is very bullish. If not, I am puzzled. 50 is the line of defence that should hold.

Conclusion: everything that can realistically happen is bullish now. Only "problem" is that if you buy at 100 and you could have bought next week at 50, you net half the amount of coins + feel stupid in the process.

We never were even going to breach $100. Banks are open again, trading will be in full swing.... And this is just Tuesday morning.

I can't even begin to imagine the stupidity of rashly selling off at these current prices at this point in the game.

some taobao sellers started to accept bitcoin
This is no news, but I bet 99% of the forum users don't know about this and they probably don't know what is Taobao.

It's pretty good news though -- Some of the sellers on Taobao are huge, making money hand over fist.

Stupid bullshit.

You missed out on $50 3 weeks ago. Buy now at $106 and be glad they are still cheap.
506  Economy / Speculation / Re: Wall Observer - MtGoxUSD wall movement tracker - Hardcore on: May 07, 2013, 03:57:59 AM
Holy shit that was a crazy ride. Bought at 103 seconds before it jumped to 111. Don't know what to think now. Still think sub 100s after this thing runs its course.

Sell for 109 wait a couple hours and buy back for 95

Hmm.. Do you think 95 will hold? If it does, we are in an uptrend, defined by the lower bound 50-79-95 (still no pics sorry)!

What if there are more coins to be sold after the "big pump of china"?
 
I say sub-100 is a buy, above 100 is not a short-term buy.

(Last time I said that, it dropped to 50 in the following day and I kind of felt sucker, buying at 86..)

Once bitten twice shy, eh? In this case, I think you might actually be low-balling it.

Anyway, these are all cheap coins.

Orders are still coming through.

Looks like people are making good use of the "lag attack" posted on reddit. Fuckers.

How would one take advantage of lag?

Because people sell at the drop of a hat.

Looks to me like 110 - 120 is a fair trading range to be honest. I think you're selling cheap.

Volume picking up on this downtrend.

If anybody cares, I cancelled my highest outstanding bid at $95 and moved it to join another lower existing bid as part of a spread of bids should this downtrend indeed make a strike for $80. I now believe that a retracement from a retest of $80 might not get as high as the last one did.

I don't think it will drop much further right now. I think people are beginning to learn their lesson...
You must be new here.

^^^^^^^^^ hahaha. Not one to talk as far as new goes but yeah.

... but, no...

All I've seen over the past few weeks are bottom-fishers. IMO it is the bears that should know by now... you can't keep a good thing down ;-)

Not at all. I've been well exposed to people exclaiming crashes every time there is a slight dump.

So do you guys think the bad news about government intervention is going to overpower the good news from china combined with the increase in funds now that banks are open.  Theoretically it looks like a time to buy but TA and the order book make me feel otherwise

It can take nearly two days to get your money into Mt.Gox, and that's sending it from a British bank, I have no idea how long it takes to get it through from a Chinese bank.  My money didn't arrive in my Mt.Gox account until the close of business in Japan the following day.  Obviously although it'll be nice if prices skyrocket that doesn't mean that it'll definitely happen - or that it won't of course.  I'm just going to wait and see, that's all I can do anyway but my funds are now mostly in BTC so if it does, then me and my half a satoshi are ready for it!

Dude, it takes all of 30 minutes to deposit fiat on Chinese exchanges. why would they wire to Gox?

I began with a set of VPSes in Japan, but actually found connection to west-coast US much better. I think a lot of locals use nearby VPSes as proxies (I know I do), and so connections, particularly https, seem to be getting throttled and blocked more often. I got blocked due to someone else on my same IP range -- didn't bode well.

Serving through CDN, I see sub-1-second page loads over 3G to W coast US. All assets will be served from CDN edge locations so it should be OK. How that scales to full-time trading will be the real test though.

For comparison, BTCChina, when not behind CloudFlare, seems to be on an east-coast Linode.

i had horrible experiences with running us-based services to the mainland. but what you say about vpses and cdns makes a lot of sense. i've only just started using maxcdn myself and haven't been able to run any mainland tests just yet.

i stress location and performance, but it really depends on what you're offering. basic trading should be fine, but if you're offering live charts and apis, then it could become a problem when serving the mainland's non-vpn userbase (especially if you're competition IS in mainland -- YOUR service will seem slow and spotty). but i'm with you, when i'm there i have 3 private vpns in the us, eu and sg and just use the one that's giving me the best performance at the time.

For the Bitcoin server -- I looked; we began with a self-hosted solution. However, the only secure way I am really comfortable with is a dedicated server under my own control -- even whole-disk encryption means nothing on a VPS. The intermediate code is relatively backend-agnostic, so I can always go back to that route if needs be. Will possibly be adding alt currencies down the road, so would need to self-host anyway.  I think the biggest draw for blockchain.info is that we plan to market it as a secure solution -- are new users more likely to trust a(nother) new exchange, or one of the biggest players on the block? I know where my money would go. It will help me sleep at night too...

i don't have any experience with the blockchain.info api, so what i know is purely from outside observation, but i just assumed so many people used the api for its "convenience" and "reliability" not so much for its security. imo security is still very much localized to your transaction server. i assume the exchange you've built will be automated for the most part, which means you will need to store those api keys on the server and at some point they will need to be unencrypted and then transmitted to the api (which will probably be via ssl). the point right before transmission will be the weakest link in your security chain. if that gets compromised, blockchain can't help you.

This is why I like blockhain... Yes we have to store the main password (encrypted, but reversible encryption means nothing) . But the second password is required for any move or send.

Btc in is automated by listening for transactions among a pool of user addresses that is created ahead of time (since addresses cant be created without the second password). Withdrawals are grouped and processed by an administrator who provides a secret to piece together the second password.

This second password is never stored anywhere, other than the split second in memory when actions are processed.

(Both passwords are long sha256 hashes of pretty obscure information combined with secrets.... So brute forcing isn't really an option)

So an administrator can't run off with the hot wallet coins (since they don't know either password), and someone owning the server can't do much with the coins, since they don't have the second password.

Obviously all comms with blockchain is SSL ( and we check the certificate each time)

I think it's a nice solution... And they make some nice fee income since they charge 0.0005 on everything, including moves. The main elephant in the room in my mind is uptime.

We could build something similar but on a VPS it would become the weakest link. So this way reduces the possible attack vectors a bit. Either way, this is just the current account, but it should make us less interesting.

Thank you for the recommendations. We have a waf and intrusion detection in place, and also run a self-built change check on all files. Agree that side channel attacks are probably the weakest link right now, but there's a lot we'll have to stay on top of. There's always a way in somewhere.



there are many side-channel attacks, but these 2 tools will at least cover the obvious and and alert you when attention is needed. paper wallets, hardened passwords, etc, etc, are a given.

i wish you the best of luck and look forward to the release

Will rise to around 130 before falling back to 100 .

If it gets to $130, we will have no problem to get to $170+.

*if*
517  Economy / Speculation / Re: Wall Observer - MtGoxUSD wall movement tracker - Hardcore on: May 06, 2013, 03:11:54 AM
Quite a nice shallow upward slope these last few days. All very sensible and nice. I hope the bears stocked up this time -- eventually there will be no going back for more.
518  Economy / Speculation / Re: Should bounce at about $100 on: May 06, 2013, 03:09:05 AM
Heres a rough chart that I just made to update the down trend I've been looking at. Lines are drawn in pretty roughly, only one I'm confident with is top one. I think we'll have price decline down off $130 level, if we reach that high.
 
Its another 1 month log chart





Oh.
Mah.
Gawd.

/thread

fitty, i know this seems ridiculous to you, but this is worth man than you think. try to be more constructive Tongue

and thanks for answering my question, that was exactly it, afb. these look pretty robust and there's no doubt that the volatility is hiding a midterm downtrend.

Thanks for supportive comment arepo. Don't know why people in the speculation forum slag off technical analysis so much.  If you don't like it go to another forum.




So, what does it take to invalidate this? If we go through $125 and stay there for for than 2 candles (4 hours)?

And will that have all the TA believers piling into the market then?

Be ready with your fiat guys...

Thanks. The ICP is the crux of the issue with the hosting at the moment. We're working on it.... red tape is enormous and we don't want to rock the boat too early.

understandable.

so where will you be putting those servers?
if you're serving the mainland, then this is critical (us and eu are really out of the question)
i've done extensive testing in hong kong and singapore (still need to test from taiwan)
hong kong had the best performance, but signapore had the best infrastructure.


On the blockchain.info api... Let's see. It will be costing me more than self hosting since they charge transaction fees on moves. The record to date of people running their own isn't great. I'm prepared to fall back on my own.

no it is not. but there in lies the challenge.
not a c programmer so i can't make any sense of bitcoind, but check out bitcoinj as well as bitcoinjs-server.
