Ask the万能的 family, I just found a bunch of wallets while organizing my wallet, which I used when playing with inscriptions, and they all have about 0.0007 of $BTC left, worth around 100U.

But I can't transfer them, the transfer always prompts insufficient balance and needs more $BTC. Is there any solution?

Could it be that I need to add one $BTC to make up the balance before I can transfer it out? 😂
