Lost all my Bitcoins?

No. Lesson to BTC DEVS - learn basics of end user experience. Drop your Microsoftian attitude, please. It's 2015.

Why should btc devs care about user's funds?

I assume they want more people to use bitcoin would be the answer.  People have different levels of technical experience and limited time/resources to learn new things in life.

I assume they want to feed their children and wifes.
And this reason is much more significant.
Sometimes it is contrary to what you've said.

I wanted to test Bitcoin's double-spending protection, so I copied the wallet.dat file to another folder. I had 1.21 BTC as my balance, and I donated 0.01 BTC, and then exited the program. I then moved the copy of the wallet.dat file back to Bitcoin's AppData folder, and started Bitcoin.

When it started, it showed 1.21 BTC as my balance, but a second later, it became 0.00.

Is this there on purpose to punish people who attempt double-spending, or is it a bug?

(All my transactions are present in the window. My balance is at 0.00 though.)

That just might not be how things work? The dat file does not contain your transactions and coins.. it is just an address, a wallet.. the coins and its whereabouts are in the chain, regardless of wether or not you have a backup. It would be stupid if you send your coins, than put back your backup and have back your coins again..

If I have a paper wallet, I can have coins on it and spend them, without having to print out a new wallet everytime I use it.. the blockchain ledger is keeping the books, not the dat files.

Double spend testing should be done without the risk of losing too much.

i think that amaclin is trying to say that the bitcoin-dev's main priority is the network and ensuring it cant be abused.
by this i mean the bitcoin dev's are the equivelent of the bank wire transfer team.. and there should be another team who program the user GUI, much like banks have a website dev team, separate from the payment network.

i personally reprogrammed my bitcoin core to be more user friendly, and there are other wallet programs/websites that can take care of the GUI side of things.
EG blockchain.info allows users to send funds, and backup privkeys. even ensuring the change returns to the same address as it was sent from.

i think once bitcoin-core is at a V1 status (not in beta), the programmers would divert the concentration from security and more towards user friendlyness.. but to me i think any naive, newbie, non miner should start off with other wallets. and later move onto bitcoin-core once their funds need to be secured away from third party services and once they learn to backup privkeys

No. I want to say that if you pay nothing for developers you should not ask anything.
Banks take fees and pay these fees to their developers.
Bitcoiners are proud of fee-free transactions.
But what is the reason for any developer to do things for free for you?

well the reason they do what they do is because it protects their own investments.. which as a by-product protects everyone elses too. their priority is security of the network. not so much the GUI.
however i do agree that if people want extra features they could request the bitcoin-dev team to set up an address so that people can send a donation to. because thats how politics works. corporations pay politicians in exchange for regulatory benefits or tax breaks.

maybe worth people who want certain changes to talk to the bitcoindev team, and the team set up a kind of 'go-fund-me' site that lists an address next to a features description. then those that want that feature to be dealt with, can fund it to happen.

[amaclin]

short-trading may be more profitable for "protecting investments"

their priority is security of the network.

Any proof that somebody of them said that?

Some people just do not want to collect donations.

i meant they need to prioritise security to ensure bitcoin itself doesnt fail making everyones coin worth nothing.. which no 'trading' will help profit from if bitcoin is worthless, so making sure bitcoin doesnt fail as a payment service with limited supply is top priority, not just for their own investments, but yours too

yes for many years gavin andresen has said it himself, along with most of the rest of the dev-team

OP never mentioned about checking his funds in explorer. Do not try unknown things always.
Do only things what you are sure about. Playing with wallet files are not recommenced even for experienced people also.

It was 2010 and 1.21 BTC was worth nothing. The core wallet.dat file now contains pre-generated change addresses to mitigate things like these. If it wasn't for these experiments we might not have this feature.

Exactly this! We need unfortunately many failures like this to learn from them and improve software and user experience of the Bitcoin. It's actually like that in every industry today all over the world. Nobody is so smart to anticipate every single thing that can go wrong. We live and we learn and I am OK with this, even if one day I might be the one that will pay the price.

Edit: And I love the option that I can have many different addresses so I can give each address to the person I wish to.

[Kakmakr]

I do not believe trusting the wallet.dat file should be your only option to secure your wallets future. I have seen too many times, how files get infected or targeted and then become inaccessible to the users.

I always resort to a physical printout of the private key to secure my coins. This is something that has to be addressed by the core developers and engineers, because many people are clueless about these technical things.   

[maokoto]

I am kind of a noob and learnt today that to make a backup you only have to backup the wallet.dat. I was surprised that it was so simple.

To restore a wallet you only have to overwrite the wallet.dat then?

[bitcoinuser48]

Very bad 1.21 BTC is very huge you lost with a double spending bitcoin error.

[UserVVIP]

Why in the world would you try and double spend in the first place? Seems like a stupid idea.

[Stephen Gornick]

The core wallet.dat file now contains pre-generated change addresses to mitigate things like these.

Right.  So why are they not showing.

Does OP simply need to do a restart with -rescan?

[kingscrown]

u will be very lucky if u get this coins back

on the other hand - you just put bigger value to BTC due to more lost coins that will never move!

[7788bitcoin]

I don't think this is a case of double spending. It is just a case of accidentally deleting a wallet.dat file. Never overwrite a wallet.dat unless you are very sure there is nothing inside (or no one will send anything to the addresses).

[BlackPanda]

This is a nightmare. you have a loss of the most important key..

It is not just simple "caring about users funds" matter. It is about creating something good and reliable for people to use.
If you have to be IT engineer to be able to manage your bitcoins well and you need to special training to be able to copy your btc, then something is not right here imo.
