You can combine those inputs by sending all the UTXOs to a single address. It's called consolidation. Best to do it when fees are low, like around 1 sat/vb.

Thanks, everyone. I’m gonna try with a few test sats.

Thanks for the heads up. But just to clarify, can an offline machine really generate proven keys, public keys, and addresses? Seems to me that doing this offline is safer than online, right?

So, I have to download something, huh? Can’t I just do it through the terminal?

Hey, Can I create private keys, public keys, and addresses using just an old computer (Windows, Mac, or Linux) that’s not connected to the internet? If it's possible, what’s the method? I figure generating a private key…

Yeah, "dumpprvkey" gives you the private key for just that address in Qt. I don’t think you can get seeds from a Qt wallet either. You could recover using the wallet.dat file or importing private keys for each address.…

When you import a private key, it usually only brings back coins tied to that key. So, did you actually import all 30 private keys? You should really use the recovery seeds or seed phrase to get back the whole wallet.

You should check the current fee rates. I saw it’s over 40 sat/vbyte right now on mempool.

Also, jumping on a trend can be risky. Think about someone who has just one product and when it’s hot, they're fine, but once the trend goes, they're screwed.
