Always been a Bitcoin fan but today I'm really, really pissed

It's my sister's birthday and she wanted Sims 4 so I paid for a key on Kinguin fucking
three days ago! And the transaction is still stuck.
What's worse, I paid the recommended fee that blockchain.info automatically adds and normally my payments go through within 5-10 minutes when I pay the recommended fees. I just ended up paying for ANOTHER key using good old PayPal.
Same with my a-ads advertisement campaign. The funds are just stuck for days. Meh.
your first mistake is using a web wallet and worst of all you are using a buggy web wallet.
blockchain.info is suggesting the same fixed fee as it was a week or a month ago irregardless of the current appropriate fee.
your other mistake is not doing a research when using bitcoin. it is not like a bank to run to them with any problem. with bitcoin you are the owner of your own money and fully responsible for it. so you need to learn a couple of "how tos" such as knowing how fees change. and what wallet is a proper wallet with no bugs like what blockchain.info has.
