Bitcoin Forum

I have been using multibit wallet for years storing the roaming/multibit folder on a backed up usb key and transferring to and from my laptop when i need to use the wallet this works fine but every time i copy the folder to my laptop and start multibit it takes time to resync this time takes longer and longer and I have now found that multibit is no longer supported/updated so i need a new wallet

I want a wallet that will let me store the wallet.dat file and the blockchain (or whatever it is i need to sync) on an usb key

can anyone tell me which wallet will let me do that

cheers

Given that the blockchain is currently 150+ gigs... unless you feel like dropping USD$70 on something like this: https://www.amazon.com/SanDisk-Ultra-256GB-Flash-SDCZ48-256G-U46/dp/B00YFI1A66

Your best bet is an SPV wallet... Electrum is probably a good choice (https://www.electrum.org/#home)... the wallet files themselves are generally less than 100KB (depending on the number of addresses/transactions etc)... it uses 12 word seed backups, so you can have solid backups... and there is a "portable" version, so you can put the whole thing on the USB key... it has fully customisable fees including "dynamic" fees and "RBF" to prevent and/or "fix" stuck transactions...

In addition, the application is actively maintained and there is a large and active user group on these boards here: https://bitcointalk.org/index.php?board=98.0

Great thanks

Outside of a hardware wallet, I would say Electrum.  Its easy to use and more importantly has great multi-sig support.

I'd recommend Electrum as well, the overheads of running Bitcoin Core are too much for me now. I'd suggest you have a good read through this thread https://bitcointalk.org/index.php?topic=1631151.0 before making your mind up. There's a lot of useful information in there.

Can also vouch for Electrum.

Though I still use Bitcoin Core on my desktop. Gotta help out the network when I can.

As an Electrum user i can only vouch for it, it has all the features a bitcoin user might need, FBR, Custom Fees, Generating multiple addresses, 2FA, Nice User Friendly Interface, Mass Pay option etc. Plus the advantage of not downloading the blockchain and getting up in minutes is the best point about electrum. It syncs up with the Blockchain via 3rd party servers hence making it act as a cold storage too. I have few 32 GB usbs containing windows and electrum on them, Its the perfect cold storage for me atleast. But if you want to store the whole blockchain then you should look for a portable solution like external hard drives, Plus the blockchain size always grows, so you will eventually run out of space. Electrum is like an swiss army knife, its size may be small but it can do everything a user might need.

My advice will be get 2-3, 32Gig usbs and install linux on them, get a copy of electrum and save the seed and use the same seed on all 3 systems, It will perfectly act as a cold storage for you. Good Luck.

I suggest this route as well.  Does not export a wallet.dat file, but because it syncs on the cloud there is no syncing time, and you can still export your wallet file and/or use your passphrase to recover the wallet on a new machine.

I suggest to use the electrum in choosing your new wallet.

for the love of god never use bread wallet.

steals transactions and they never show up on the other end

Hot wallet and Hardware wallet would seem to be the best currently offered as of October 2, 2017. My personal preference would be Hot wallet since it has the best mobile app but you are free to choose any one of them.

I would like to know how Electrum performs compared to other wallet.

just try xapo , blockchain , coinbase wallet or hardware wallet. si many wallet for your bitcoin. those wallets is very high security and easy to use but high fees also but it is okay as long as your fund is safe right.

The best hardware wallet that I know is a Trezor ! This wallet will help add extra security to Bitcoin. It provides safe, secure storage for any business or person who wishes to hold bitcoin. The ultimate in ease of use and super high levels of security. A Bitcoin safe if you like. Trezor keeps private keys on its device and signs transactions through hooking up via USB. So you will need a wallet such as Mycelium on your phone or desktop. Trezor lowers the risk of your private keys being discovered even if your PC is compromised by malware.

I am curious, do you know (NOT do you believe or have an opinion...) that the same electrum seeded wallet on 3 machines will perfectly update all future transactions?

For sake of discussion let's say there is no importing of keys or scanning of paper wallets, because clearly that will cause the databases to be out of sync. Let's say there is just Electrum-generated activity.

I have Electrum wallet(Seed XYZ) on L1, L2, L3.

10/1/17 6 transactions on L1.
10/2/17 3 transactions on L2.

10/7/17 what shows on L3, L1, and L2?

Assuming L1, L2 and L3 are all correctly connected to Electrum server(s) on the BTC network... and that those server(s) are not lagging and/or poisoned/malicious etc... then L1, L2 and L3 will all show exactly the same history/transactions.

This is essentially because you're just querying transaction history for a given set of addresses from the blockchain via the Electrum server... and, theoretically, they will all return the same transaction set for a given address as their blockchain datasets should be identical.

What they might not show is the same "labels" for addresses/transactions... as these are kept on your local system (unless you use the LabelSync plugin)... however these can be exported/imported from with Electrum relatively easily if you so desire.

I do not know about wallet.dat, but I'm using the blockchain.info. It seems to me quite reliable. I'm suspicious of multiwallets, but most of the money is stored just at the trade markets.

Loads of wallets out there today(as long you are in possession of your private keys you are good )... though its a good practice downloading node, encrypt and take a back up is safest without any doubts plus you are helping build network even stronger... but if its web wallet you are seeking blockchain.info is reliable lately I've seen Jaxx and bither becoming popular among my network

According to me the best wallets which are successful with least negative reviews are
1.Blockchain(any amount)
2.Mycellium(for decent amount)
3.Xapo(for small amount)
these three are versatile user friendly and easily adaptable

i’m newbie here but i try many wallet and till now Blockchain.info Best one Because it support two coins and have low fee

The fee is decided by the network not the wallet you're using (in most cases).

If you want to store a high amount, I suggest you look at something like electrum instead (www.electrum.org/#download) which is a bit more secure as it's software on your computer instead of something that's running on the cloud - for small amounts blockchain.info is fine.

No... the fee is not "decided by the network". The fee is entirely decided by the user and/or the wallet generating the transaction.

You are free to use any fee that you like regardless of the current condition of the network, like how many transactions are in the mempool or what fees other transactions are using...

However, what people need to realise is that if you choose to ignore the state of the network and use a "low" fee compared to the majority of unconfirmed transactions, your transaction may sit in the mempool for an extended period of time as miner's tend to prioritise transactions based on the fee used... This will become even more important as the block reward decreases with each halving.

In choosing a new wallet, there are a lot of factors to be considered. Firstly, of course is the security because not all wallets are well secured. Second, the convenience of every transaction, and last is the consistency of the services.

Totally agree with you on this one. If you don't want to spend 100 bucks on a hardware wallet or don't want to download the whole blockchain, electrum is the way to go. I've been using it since I got started half a year ago and I'm very happy. It's everything you need with on a super lightweight wallet. Definitely a strong recommend.

I use paxful. Because I love to trade my coins... Love it..

I use Exodus, it is very user friendly and can store many coins inside.
Simple but powerful

I recently went from Multibut to electrum aswell. And so far i like it very much.

I will recommend Electrum wallet for you, cause blockchain.info still takes time too for syncing and you will need lots of gigs for storage, Electrum will be a better choice.

Wallet hardware, in my opinion is not very good, some people make mistakes and this is dangerous. but it is a choice and everyone is free to choose.
