My password consists of 2 words 1 is in English 1 is in another language there are 2 numbers and 1 special character in the end.
Hackers use word lists. A simple program tries 5000 combinations per second. State actors probably have 1.000.000 or more passwords per second.
I have tried in a website which calculates how much is needed to crack it (the RAR) in that website. It says to me that even with 100.000 PC with 500.000 passwords per seconds it needs about 12.000 years and a bit more to crack. I think this is safe, as the computers there are cluster computers and not just 100.000 pc connected to each others.
12.000 years is off, because you use words from English language. Hackers do not need to try every combination like abCD$!. It also assumes your computer is secure and you don't have any programs that spy on you. Even (state-owned) computers without internet can be hacked, like that system in Iran.
A good password makes it harder to access your computer, but not impossible.
If this file goes in the hand of a national security agency how long it will take approximately to crack it ? If it is more than 1 month for me is OK, I will transfer my bitcoins to another wallet during this time without problems.
Edit: The English word cannot be found in any dictionary, it's a special word , people use it rarely and I checked a few dictionaries and couldn't find this word there.
Those guys are really awesome

I bet they can do it in under 30 seconds using automated tools.
I would need about 5 minutes, 4 to grab a cup of coffee and 1 to open your file system.
