Just to clarify about the extra zeros. 0.0003 or 0.003?

But anyway, since this is not for spending money, better not to withdraw it but instead to add some more. because if that 0.0003is real, I can say that it was enough to pay for the fees and probably had nothing left for you. Thus, if you have money left, make some additional.

You don't have to worry about losing it since it was just a few sats, and I don't that you even remembering that when the price still low.
