Topic: Locking a wallet so I can't withdraw coins (Read 4232 times)
I too have faced the same problem i too save money and end it up by spendong all the moneg on something foolish but it will be more harker if you try to think something now.i just convert them into fait and i do not spend any money and its working now
I would recommend examining your desire to withdraw/spend the coins to begin with, alternatively checklocktimeverify is in place for this.
What you're describing is centralization so no there isn't a wallet like that. If there was I wouldn't suggest using it. Maybe it's just time to be an adult and save some money in a separate wallet? Make up a paper wallet and put it somewhere inconvenient so in order for you to actually spend it you need to do step X Y Z (go to your grandma's house, go in the attic, open a safe, put in a password... whatever it may be) or put it in a safety deposit box so you'd have to be to the bank with your key to withdraw anything.
I have the same problem so i was thinking of buying a nice funded casascius coin one day then i would never want to peel off the hologram until 100% needed because once it's peeled there is no way to replace it.
The coin will still have value too after you spend the bitcoins.

Whoa...you do realize you'd always be able to get a premium over spot by keeping it intact and selling it whole right? Very few situations warrant defacing a collectible coin that only gets more collectible while idiots rip away the stickers and devalue them. They have WAY less value after being spent than they do intact and loaded by the man himself. You've got a hero account, consider selling it intact for BTC in an auction here...you'll get more than face value every time, and if you're willing to sell on ebay, you can make a lot more than spot price, just be damned sure to ship it with the crazy lock and key shipping that must be signed for by the recipient only. Ebay has your back if someone try's to scam you and you can prove it.
After seeing all reply i think only two options are better, one creating a multisign wallet and give the keys to your friends or family members and then when ever you have reached your goal, you can get the keys and then you can sell and fullfill your dream.
Another one is create a paper wallet and just put it somewhere where you reach only after you have attained your goal. You can add in this like just put it in a box or make a wall frame and handover to your friend or your family member and just tell them handover when the target is completed.
Apart from that other ideas are just too much complicated and never tested.

I realized a possibility (the 1000 BTC giveaway gave me the idea):
1. You start saving Bitcoins in Address A.
2. You create a raw transaction sending10 BTC 0.001 BTCfrom Address A to Address B.
3. Do not lose the private key for Address B!
4. Throw away (!) the private key for Address A (Remember: Satoshi recommends never to throw out a private key!)
Now, when you have exactly 10 BTC in Address A, you can broadcast the transaction.
I haven't tested it though. Try at your own risk.
I changed 10 BTC into 0.001 BTC because it feels too risky to do. I'm also not sure if you can use a raw transaction for inputs that are not in the address yet. So this may fail. But I'm curious to know if it can work.
Won't work. You would need to know the txid and index of the inputs beforehand and you won't know that until you actually receive the Bitcoin.1. You start saving Bitcoins in Address A.

You can create a transaction with the SIGHASH_ANYONECANPAY sighash. This means that you sign the transaction but ignore other inputs. Adding additional inputs to the transaction won't make the signature invalid.
This means that you can merge 2 or more transactions together. You create a transaction with (SIGHASH_ANYONECANPAY OR SIGHASH_ALL). This means anyone can pay and also that you are signing all outputs.
The first transaction could be
Input: 0.11 BTC, Output: 1 BTC to
Signed: (ANYONECANPAY | ALL)
Once you have verified the transaction, you throw away the private key for signing the input.
You can create more transactions like the first one. Once they all add up to 0.11 BTC (or more), you can merge them into a single transaction. This only works if all of the transactions pay to exactly the same output. You can include a fee by having the inputs larger than the outputs.
Since nobody has set something like this up already, there is a risk of bad coding. If you mess things up, then you can't get your money back.
You could put the private keys somewhere inconvenient rather than destroying them, at least for the first attempt. The actual first attempt should use as little money as possible (testnet coins would be even better).

Electrum has an option in which you can freeze an address and you can not move the coins from that address anymore. This has also a downfall as its you who control the wallet and you can unfreeze it any moment and keep using and withdrawing this coins whenever you like. Unfortunately the thing that OP is looking for is still not yet implemented and I don't think it can be done. For this to be done are needed 2 persons and when 2 persons use the same wallet, much problems will arise no matter if they trust each other the temptation of using the coins will always be big.
I'm not really sure if this should go here or off-topic, but I think it should be here 
I was wondering if there's a way I could deposit bitcoins to a wallet, address, and I wouldn't be able to withdraw them until I reach a certain sum
I'd like to start a fund to save money for a car, however, I always end up spending my money instead of saving it
Is there a way to set something up, where I could be able to withdraw the coins only when the balance of the wallet reaches 10BTC or something like that?
For example, generating a password that would be given to me once the balance hits 10 or something like that

This is what I want also. Something that I dont really have an access with. But I got this idea of creating and account with my wife's name on it. I told her to change the password and dont tell me until the time comes. It is still growing up until now. Actually I forget it sometimes but my wife tells me that she wont forget the password. Somehow I had a clue but wouldn't try to open it still.
set a goal , to reach your target , then save it on cold storage and paper wallet , set a remainder on your laptop one reached certain days to give you remainder. there are some wallets which gives double security options , you need to choose which is suitable for your country 
What I can think of is something like an online wallet you access with a web CP. It could be a regular wallet, but your web CP access could be restricted.
Then let a trusted friend or someone you know who doesnt know btc to hold a password for that account.
Then your trusted friend loses the password, and you can say goodbye to your good friendship and your money. Not a good idea!Hahha
Yeah, better trust your family. At least give all of them the passwords, 3 each. I don't think all of them will loose it right? Hahha And it is more secure I suppose. Great idea right ?Then let a trusted friend or someone you know who doesnt know btc to hold a password for that account.

Their are so many method which you can use it , like one multisignature wallet where you will be dividing the key with 2 or more peoples so if you want to open the wallet then you will be needing all keys to open the wallet, other one is paper wallet you can convert all your btc to paper wallet and when you need it you can convert to wallet and go on. Apart from that if you can expense some bitcoins then you can use any trusted escrow person to lock you wallet and keep the key with him for the period of time what you are asking it. Other then this i dont know the option of your problem.
I think you can just make another wallet. Then let a trusted friend or someone you know who doesnt know btc to hold a password for that account. If you want to access that chain, you can just go with him to open the account you made. Until you are satisfied with its earnings, don't ask yet for the password.
Yeah you could send it to a trustworthy escrow member.
There are some people on these forums that have held tens of thousands of dollars in coins in escrow.
But remember, if you tell them to hold your coins until a certain date, and they are providing a reputable service,
there is no way they are going to release the coins early.

Escrow is the way to go.
Tell him how you want him to manage your funds and that's it. Get a reputable escrow here in the forum.

You're probably interested in checklocktimeverify
I think in the future we'll see wallets with a feature to lock your funds for a certain amount of time.
I'm not sure if a certain balance could unlock it though.
...
hmmm, so simple, and not a bad idea
I could have 1 key, give one key to a friend and one to my sister telling them not to give me the key if I don't have 10BTC on an address
Nice
Multisig could be helpful.
Create a multisigwallet where 2 keys are needed to unlock the funds.
Or, 2 out of 3, or anything else.

Sounds pretty risky. Could work short term, but the longer it takes for you to save up 10 btc, the higher the chance one of them will lose their key (or forget where they saved it etc).
