Hello crytpo team

I need to know if there is any website out there that provides the option to import my wallet.dat file or even my private keys into an online account, such that I can access all my coins stored in my dat file.
Why i am asking this is because i have several coins which i would like to trade but can only get it to the exchanges by installing the coin clients and syncing the blockchain for each. This is going to be time consuming to get it done that way and not to mention the intenet data usage.

Is there any website that allows importing my wallet or private keys for any of the cryptocoins currently live. Many of the blockchains are huge, don't sync because of node or some other issue.
Are there any other options that i have?
Any feedback welcome.

Thanks to all

I think it'll depend on the coin in question. For example, litecoin has an electrum version that allows you to import private keys (AFAIK).
There are also a couple SPV wallets like coinomi that allow you to manage a couple altcoin wallets from your mobile device without syncing the blockchain behind them (they do not allow the import of a PK tough, and it's a mobile wallet witch might lessen your security).

I'm pretty sure you won't find any online wallets that allow you to directly import your altcoin wallet.dat tough... I don't think there's enough money to be made to develop such wallets (i'm not sure tough, maybe somebody will point you towards one).

Thanks for input.I thought as much myself. However does anyone think that it might be a good idea to just sell off each wallet.dat file using escrow in places like openbazaar or bitrated. Does anyone know where I can maybe do this besides those two places. Or does anyone know any other online multi wallet provider where I can import my dat file or my private key.

selling your wallet.dat might be possible, the only problem would be trust and it could be a big hassle...
The fact is that when selling a wallet.dat, you're basically selling private keys. This means that both you and your buyer have access to all private keys, and in case of a dispute, the escrow will need to manually verify the wallet.dat by installing the client, syncing the blockchain,.... As long as the wallet isn't emptied out, outputs can be generated by all parties involved (buyer, seller and escrow).

It's a lot cleaner and easyer for all parties if you install the wallet software, send the coins to the buyer and then destroy the wallet.dat as soon as it's empty (or hold on to it, you should in fact never destroy a private key). In case of a dispute, you can just send the transaction id to the escrow, and he can use an online block explorer to verify if the output was correctly generated and release the funds directly...

I'm not saying selling a wallet.dat would be impossible, i just think it adds an extra layer of complexity to the whole deal, and might actually make interested buyers turn away... It's just my personal gut feeling tough... Maybe i'm overlooking something.

Thank you very much Merelcoin for all the advice
I guess I have to weigh my options now and see which way to go.

Yesterday I had a look at coinomi but in that option you need an android phone.

Then I also noticed a site on the net called cryptochainer which provides complete blockchains which you can download in a zip file and use with your own wallet.
I guess my options are limited.
Thanks.

You can save time on some coins by downloading a Snapshot or a Bootstrap.

Kiklo's Bootstrap.dat & Blockchain Snapshot for Proof of Stake Coins

For a List including PoW coins, there is http://cryptochainer.com

 Cool

FYI:
If your bandwidth at your location is metered where it costs more ,
then get a remote VPS for a month ~$25, once synced with a block chain upload your wallet and then send your coin to an exchange.
Once you get all of your coins transferred cancel the VPS.

Currently there is not such a web wallet, which offer this, even online altcoin wallets are just a few. And this is also the question, how safe the online altcoin wallets are ?  Wink
