Transaction stuck and "double spent" after increasing the fee

[helenp]

Yesterday I sent this transaction with a fee of ~0.33mBTC:
https://www.blocktrail.com/BTC/tx/91e841994f648767a07ab8b19ceffd4fa7cdf3de727227c2707ff01d9489d970

This morning I saw it stuck. After reading a little, I raised the fee to ~0.41mBTC.
This fee was supposed to make the transaction proceed within 25 blocks maximum,
but it is still stuck with zero confirmations and also marked as double spent.
On Bitpanda, the receiver, both deposits appear as "processing".

Help, please? I'm very earnestly at a loss, since I believe I followed the nominal solution.

Ooooops.

After writing it occurred to me to look at the news and realized that I'm a cog in a giant party.

Still, it'll be appreciated if someone can let me know whether I did anything non-optimally.

PS: Originally I planned to ask the following philosophical question after/if I received answers.
I think I can ask it now since it's already old:
With bitcoin getting increasingly popular, is there any provision in place for future huge transaction flows?
people after all will need the thing for actual transactions if it is to be trusted as a tool.

Transaction processed now.
Although it's still "double spent" on blocktrail. I'd be happy to understand how this gets fixed
or whether it matters at all.

Your ORIGINAL transaction shows as being double spent... but technically, that transaction is no longer valid, as the inputs have been used by the confirmed transaction.

If you look at other block explorers, it either doesn't exist (they dropped it)... or it shows as "removed": https://btc.com/91e841994f648767a07ab8b19ceffd4fa7cdf3de727227c2707ff01d9489d970 to indicate that it was effectively superseded by your new transaction with the higher fee.

The simple solution is: Don't worry about it. Your new transaction got confirmed... everything is fine
