if incoming money is automatically registered to users playmoney account, then only one receiving address would be enough, as long as it i added to the right user  how would that be done ? It can't be done. You would have one 1 address per user at a minimum. You likely would want to have multiple addresses per user so they can gain some psuedo anonymity. what about bitcoin client feature for proving the address ownership ? user sends btc to cold storage then logs in to my service copy/pastes his signature to his account requesting funds to be added then my side checks the blockchain, and if signature is valid, amount is written to users account balance would this work ? |

Oh, it sounds like you are trying to avoid having to sweep funds to cold storage. Normally a service that has a hot wallet and cold storage will sweep excess bitcoins to a cold storage address. This is described here:
So you are wanting the incoming payment to go directly to addresses from your cold storage.
direct deposits to offline wallet and if possible, all to the same address amounts received can be extacted from blockchain, but how to connect that numbers to respective users automatically ? and what if I want to have a p2p service ? how to maintain database of user accounts ? |

If I understand correctly, you want to use an offline wallet, but you still want the ability to automatically receive payments which will credit to user accounts.
yes If you assign a public key to each user account, then you can monitor each public key's transaction log to look for incoming transactions (since all transactions are public). The difficulty will be in automatically generating new addresses for new accounts. You could pre-generate some keys in the offline wallet, but you would need to generate more when they have all been used. As far as coding it, you might could save some time by using blockchain.info's API to monitor for new transactions: http://www.blockchain.info/apiif incoming money is automatically registered to users playmoney account, then only one receiving address would be enough, as long as it i added to the right user how would that be done ? first time user creates account, my only receiving address is displayed, but how will I know to add money to exactly his account ? Are merchant solutions offering this kind of service ? and I would not be interested in users actual identity ... |

If the coins are sent to MtGox, they're only as safe as MtGox's security allows them to be.
but this is much more than I could provide, I mean, mtgox account with yubikey all I would have to do, is to keep some database backups on several locations |

thanx for reply
actually, I wanted to know if this is automated and code is only copy/pasted :
user sends btc, and his playmoney account is topped up without me having to do anything.
I guess it has already been solved, but I have to check before committing myself to a project...

is it possible to receive payments to mtgox or armory watching wallet
and then automatically assign numbers to users accounts ?
while actual coins sit safe and are sent manually on request

to copy the best traders' moves on bitcoinica
etoro offers something like this,
after making a deposit,
just decide what % of your money will you use to follow trades of top earning traders
I would certainly do this.
Actually, I do not understand how this is sustainable, but it seems to be, so, why not ?

it's very simple. there are always cycles of high and low volatility. now we are in low volatility. soon we will see a massive move
so, we are all waiting for the most expected bubble in history of bubbles ? |

instead of start using real moneys,
they trade new kinds of commodities, reinventing the wheel
tems, time barter, this is so wrong...
I mean, to go and create a tems system, advertize, do so much work, and not find out about bitcoin ?

are they behaving (locally, in Greece) as "expected" ?
I mean, food probably is up, but housing and PMs ?
there is one interview on youtube, a guy from Agentina last decade
said silver shot up 500%
is this verifiable ?
so in collapse, it still is much better to actually hold food and what not,
then PMs & real estate
so, unless holding actual cash in hand, all other are fucked ?

Woo! Another potential adherent of anarcho-fascism! https://www.facebook.com/pages/Anarcho-Fascism/120635897984051Anarchism through fascism! Let's get it done! Beef up CISPA, enforce it with death patrols who call air-strikes on datacenters, ban computers! Eliminate tax deductions, criminalize commerce, mandate citizen-enforced rectal searches at bus stops! *clears throat, straightens tie, quietly goes back to spreadsheet reconciliation* I think u didn't understand me, I am against all this shit with taking our rights, just sayin' people will get boiled like a frog, little by little... |
