Re: "Stress Tests", Spammers, Attacks: Burning My Butt. Very Bad.

any one knows when is the next stress test going to be ? i would like to be ready before sending out any transactions with manual fees last time i was stuck for like 6 hours with no confirmations.

Only 6 hours? Hahaha dude, i am waiting for more than 48 hours now and still not even one confirmation, WTF Shocked

uhh, did you pay some TX fee? can you please post here TX of transaction? this seems very unlikely to me tbh. during last test, I tried by myself to sent 0.1BTC with 0 tx fee and it was done in 15 hours..

https://blockchain.info/address/1BnvHarta94JvXrY7oT272qTBEvgMdRk2S Here it is, 49 hours and counting,the fee was 1114 satoshis. I dont know should i laugh or cry hahaha

your tx fee is very very low... this could take some time. even without an attack

I know and i regret now. Is it possible to undo things? to send somehow a bigger fee for that transaction? sorry if it is a stupid question but I am desperate.

Nope. Bitcoin transactions are irreversible just so you know. You have to wait for days or possibly weeks for that to confirm. In some cases, it takes a couple of weeks before a transaction is confirmed, especially if the sender put no fees for it.

in theory, he could just double spend it with a higher fee. if it goes through the other one will be invalid

You can't double spend it, since a node that has the "old" transaction already in their mempool doesn't accept the "new" transaction.
That is to prevent double spends.
