Which wallet can import keys? Bitcoin core is too big, Blockchain is online

it is blockchain.info and please stop calling it blockchain

What happened if he called it blockchain and not blockchain info? He can to call it what he wants and when he says blockchain I think everyone can understand.

yes, and nobody is stopping anybody from calling it whatever they want Cheesy

but it is wrong and confusing.

blockchain is the public ledger of all Bitcoin transactions that have ever been executed.
blockchain.info is a web wallet (you can use BC.I for short if writing a .info is too hard for you)

that is why it can become confusing especially for new member who may read it.

Also remember that messing with ECDSA private keys is very dangerous and can result in losing bitcoins, even long after the import.

i have no idea what this means.
unless you are making your own code for creating a private key, you can not mess with Elliptic Curve Digital Signature Algorithm of the wallet!

Mycelium used to offer the option to recover wallets by inputting the words from the mnemonic phrases but I reinstalled it yesterday on my phone and looked for that option again and I couldn't find it anywhere. Did they remove that feature after the updates? The wallet seems quite different from the last time I used it and now features a lot of fiat-based trading?

My mycelium wallet is up to date and the same wallet features works in me.

You can also use Mycelium and steps are simple and also in Mycelium you can import keys from paper wallet and also partial spend from cold storage but when using this last one, the private key in memory is destroyed so the paper private key remains somewhat secure.

Also remember that messing with ECDSA private keys is very dangerous and can result in losing bitcoins, even long after the import.

Just share my experience, i think you can try mycelium wallet, because i have used this wallet everything went fine, there are many features are like sign massages, scanning private key and it is for android. But i don't know it is suitable for you or not.

I have been using Xapo and blockchain.info. Blockchain.info does accept importing keys to it. Any idea on Block Trail? It the fees is more compared to any other wallet, that's what I have heard of. Just try them out if you wish to know more.

... it has option to set the fees manually from its settings menu goto:
Tools > Preference > Transaction (tab) > (check dynamic fee for a dynamic fee and uncheck it to set it manually)

I tried setting the fees manually on electrum, but it would not go lower than 0.0001btc. Just kept saying the transaction won't be broadcasted, guess manual setting is not so manual after all.

if you set the fee too low like 0 and a little above it, the priority of your transaction will also be too low, so it will never be confirmed. so Electrum has set some kind of block to prevent this kind of transactions finding their way to the network.

but you can still set the fees to even zero and make the transaction, sign it and broadcast it in another place. either another wallet or an online block explorer that lets you broadcast txs to network even if they have 0 or low fee.

Under the HD wallet UI interface, the way you import private is to sweep the coins to the wallet itself, which is recoverable from the backed seeds.

I know that of course. Sweeping is not importing. I want to import an address, not sweep it.
With two wallets I can now do it.

Mycelium wallet features HD wallets. You can import and export privatekeys. Make several different wallets and save them in a single backup. It is lightweight. You can use it as an offline wallet also. They also allow you to set your own fee just like what you wanted. Only downside is it is a mobile wallet. Overall it is a good wallet to use daily.

3. I went for Electrum with 2 wallets. One to import, one for normal use. When I import I send change manually to the other wallet. They should allow imports on a normal wallet but they do not allow it.,

if i am not mistaken, it was removed in order to prevent confusion and possible loss of your coins. because if you have a wallet with seed and then import a private key directly to that wallet and continue on, but someday lose access to that wallet and want to recover it using the seed you will recover the original wallet but not the imported keys so any coin in the imported keys will be lost.

You could always use Vanitygen to generate new addresses in bulk (though they would be in cleartext in a file on your hard drive), to import into Electrum as needed. You're quite right that the "Import mode" wallets don't have the auto-generate functionality that the seed wallets do

1. Core is too big? Prune it.
2. Blockchain.info is online? Set a secure password and make backups.
3. Electrum can import and generate new wallets. Simply click import at the top to import, and when you open Electrum for the first time. You will be prompted to generate a new one.

1. Still needs resources and is slow.
2. It's still online on a webpage.

Multibit I did not like.

If I import keys, I do not get a deterministic wallet. If I send from an imported key, do I have to manually import a change address?
I stopped without trying after reading this. I will try it and report back.

you have two options (option 1 is recommended)
1) make a normal wallet with Electrum (which has seed and everything) then use
Wallet > Private keys > sweep
to send the bitcoins from the imported private keys by spending them and sending to an address from your wallet
2) start a new wallet
File > New/Restore > (give name) > (select restore....) > enter a list of private keys
this way you will have access to the private keys without spending them but this wallet does not have a seed so you can not recover it with seed and you have to back up the private keys individually.

I will try Multibit too. Is 'Classic' different than 'HD'?

people on Multibit board can help you more but AFAIK HD is the newer version of multibit which is being developed and classic is the old version which is usable but no longer updated.

I can only answer about Electrum not generating. It can generate, just click create new wallet and you will have a new seed and a new wallet. Electrum can create as many wallets as you like this way.

I have imported one private key to a new wallet. This works.
When I make a transfer, it generates a new change address. But this is not deterministic. Do I need to create an instant backup after every transfer to add the change address to the backup?

I changed it.

take a look at Electrum again. it has all the things that you say you need.
you can import keys into Electrum from other clients: http://docs.electrum.org/en/latest/faq.html#can-i-import-private-keys-from-other-bitcoin-clients

i don't know what you mean by generate but it is a wallet and when you create a new wallet it generates a list of addresses for you to use!

I read that too:

Quote

If you want to import private keys and not sweep them you need to create a special wallet that does not have a seed. For this, create a new wallet, select “restore”, and instead of typing your seed, type a list of private keys, or a list of addresses if you want to create a watching-only wallet.

If I import keys, I do not get a deterministic wallet. If I send from an imported key, do I have to manually import a change address?
