Bitcoin Forum

I recently found out that my wallet Multibit HD 0.4.1 is considered as buggy and in some cases all Bitcoins stored in it can be lost.

So i did some research and found out more about wallets. I saw only two of the main wallets download the whole network (full bitcoin Client) Source: https://bitcoin.org/en/choose-your-wallet
And i think this is waht i want.

Now my question is:
Shall i chose Bitcoin Core or Bitcoin Knots ? It says Bitcoin knots has more features but not as well tested.
Someone has experience with these two wallets and can recommend something, with a statement why he recommends?

Thanks in advance.

Bitcoin Knots is a fork of Bitcoin Core that is maintained almost exclusively by luke-jr. He maintains a few additional features that have either been removed from core or don't exist in core. Knots primarily includes additional features proposed for Core in Pull Requests but have not been merged into Core yet. It is constantly updated with Core codebase so it does have whatever features on core.

Unless you think that you will use any of Knots' additional features, I suggest that you stick with using Core.

I hadn't heard this about MultiBit.  Are you sure you heard this from a reliable source?  Can you link to where this has been demonstrated?


Make sure you have a few hundred gigabytes of storage space available to run it.  Also be aware that after initial install it will take a while to synchronize (anywhere from a few hours to several days depending on your computer system).  Most importantly, make sure you create a backup of your wallet after you install it (and any time you change your password) and store it in a safe place.


You may also want to consider Bitcoin Unlimited. It is currently compatible with Bitcoin Core.  If, in the future, there is a decision to allow larger blocks in the blockchain, Bitcoin Unlimited is already ready to accept them.

Wallets that download the entire blockchain are very resource intensive. If what you're looking to do is simply transact bitcoin I'd suggest you stick with something other than bitcoin core.

Just look in the Multibit section on bitcointalk, I think 90% of threads are about people who lost their BTC or have other problems with it. https://bitcointalk.org/index.php?board=99.0 (https://bitcointalk.org/index.php?board=99.0)

Compared to f.e. the Electrum section, where those problems are more or less rare.

To all the others, thanks for the answers :)
I thought it was like 50GB for entire block chain, that would be ok for me, but a few hundred GB, i might overthink this desicion  :D

The blockchain is currently ~110 GB in size, so that is the amount of data you would need to download and store. However you can enabled pruning mode which will delete the vast majority of the blockchain on-the-fly to maintain a set number of blocks on disk. By default it will keep the last 288 blocks. Overall, pruning reduces the space used to ~2 GB with no decrease in security. You will still have to download the entire blockchain, but you will not be storing all of it.

How long does it take till those 288 blocks would be replaced ? I assume it would be good if i would turn on my PC that often, so I always have at least some parts of those last 288 blocks stored ?

288 blocks is ~2 days of blocks.

BU nodes got banned because of relaying the block with excessive size

Is Bitcoin unlimited a Wallet, or a spcific type of node ?

Both. It is based on Bitcoin Core, so it is a full node. It can also function as a wallet. However BU uses modified consensus rules so there are circumstances where BU built blocks and nodes are incompatible with Core blocks and nodes.
