Hi everyone,

So, dumb question, of course I should if I can...

However, this is being considered because I need to make a large transaction as safely as possible.

I have a p2sh SegWit BTC paper wallet and need to move it all in one transaction to a Ledger hardware wallet.  I need to get it off paper and into a proper, secure BIP39 wallet.  This is over 30 inputs and a mix of all 3 formats (Legacy, SegWit and Native SegWit) with a total raw data size of well over 30,000 bytes.  This is also a life-changing amount of BTC.

Unfortunately I'm learning the not-so-positive details of all this later rather than sooner.

Is setting-up a node on a solid computer and importing the private key into a Core wallet be an ideal, dependable and safe way to eventually move these funds in one shot?  Would this be the best possible option for such a transaction?  I don't care about massive transaction fees.  Is this idea unsound for some reason given the details of the existing paper wallet?

People have suggested importing it into Electrum or just sweeping it with Mycelium but I need to get responsible and do the optimum thing for a change.  I can't get my copy of Electrum 4.1.2 to validate in GPG suite on my Macbook Pro running Mojave, when I try my Finder window just flashes once.  No doubt I'm doing something wrong but it immediately concerns me.

So, would setting-up a Core node be the best way to ensure the funds in this wallet get safely transferred to my Ledger?

Thanks to all for reading and any comments!

All the best

Hi everyone,

Can anyone please comment on any maximum transaction size that Mycelium would not be able to handle?

I have a p2sh SegWit paper wallet with well over 30 inputs (mixed with Legacy, SegWit and Native SegWith inputs) and raw data size of well over 30,000 bytes.  I need to move this to a Ledger-generated address on a new hardware wallet.  Also, this is a life-changing amount of BTC.

These days I suspect a significant transaction fee to move it in one output, which I need to do, in the hundreds or thousands of $ to have it confirmed quickly?  Cost of the transaction is of no concern, only that the wallet can handle it easily without issue.

I've always had very good luck using Mycelium which is the only reason I'm considering using it for this.

Would Mycelium have no problem sweeping this wallet and with this transaction in general or is it best to consider other options?

I'm an idiot learning the hard way in this regard and in a bit of a spot so thanks for any comments on this.

All the best
