Best BTC open source wallet

[Outhue]

What's the best BTC wallet that can run on desktop and fully open source? I'm mining through Nicehash website using GPU but getting paid in BTC and I want to store BTC as long as possible that's why I create this topic here, hope I'm in the right section.

1. Please move this topic to wallet software. You have a link on bottom-left of the page for this.
2. You had good answers already in another topic you answered, right before your answer there. Do you want to learn or just spamming around?
3. For your question:
 * if you are OK with downloading 400+ GB of data (the blockchain), Bitcoin Core is the answer.
 * if a simple wallet is what you're looking for, then you should look for Electrum or maybe Sparrow Wallet. There are various pages about safely verifying your Electrum download to stay on the safe side, follow that and you won't cry later.
4. Please read this post of mine. Open source wallet won't necessarily keep your money safe.

Let me ask you about Bitcoin Core data.
What is the growth progression of this data? How many GB increase per year? I guess that the increase every year is more and more due to new users.
Hardware wallets works with Bitcoin Core?

I don't know. It depends too much on how many transactions are made, hence I would not expect neither too accurate info, nor a good prediction.

Hardware wallets works with Bitcoin Core?

In theory they (or some) do. In reality I found the procedure complicated and decided to install an Electrum server to work with my Bitcoin Core (some reasons are here). This way I also installed a local block explorer for my use, this way I use Electrum with my hardware wallet - and I am much more used with Electrum than Bitcoin Core and Electrum works very easy with my hardware wallet.

If OP would have been asking from start in relationship with hardware wallet I would have been recommending Electrum from start (with or without local server). But he didn't.

There is no universally best Bitcoin wallet for everyone and it all depends what are your requirements.
If you run full node than best open source wallet is Bitcoin core, for light spv wallet most people use Electrum wallet, and then you also have open source hardware wallets (Keystone, Passport, Trezor...).
For storing coins long term maybe one of the best option is using cold storage offline air-gapped computer.

Hardware wallets works with Bitcoin Core?

You can connect a full node to certain hardware wallet software.

Here is the guide on how to do it for Ledger Live. Apparently, it's not working properly because there is a notification at the top that informs us that the feature is not supported in the newest version of the software. Maybe it still works with older versions.

I am not sure what stage of development Trezor's full node implementation is. However, you can download and use Blockbook. With Blockbook you won't have to connect to Trezor servers and you can use your own.

If one indeed wants to have a Bitcoin full node and use it with a hardware wallet I think that it could make more sense to install an Electrum server and use it with Electrum (or maybe Sparrow), especially as Electrum works very nice with hardware wallets (and unlike some other options it's also open source).

There is no relationship between number of Bitcoin users and blockchain growth. The blockchain grows only by the rate of transactions available to mine into blocks. A small number of users could submit a lot of transactions, of course a large number of actually active users would create a proportional number of transactions.

Worst case prediction (not accurate, though!) is roughly on avarage every 10 minutes a block of physical size of maybe 1.7MiB (when I check last blocks, their max. size is somewhere in this ballpark): ~87GiB/y worst case, actual growth is less, I guess 40-60GiB/y

There are some graphs out there, see this one e.g.: https://www.blockchain.com/charts/blocks-size

You asked for a desktop wallet, but for storing BTC as long as possible, I would instead recommend some sort of cold storage.

Either an open-source hardware wallet or something DIY like an offline seed, created from a laptop running Tails live off of a USB stick. If this sounds complex, have a look into SeedSigner - that's the same thing (tiny offline computer), but basically preconfigured and easy to use.

If you buy a hardware wallet, to keep your privacy make sure to install Bitcoin Core and electrum server on any computer that you control; then connect to this node^{(by entering the electrs Tor URL)} from any software that is compatible with the wallet of your choice. This software could even be a mobile app, if your hardware wallet supports mobile phones.
