user123364: I found an old BTC wallet. The password should have about 8 characters but forgot it unfortunately. Is there a realistic chance to recover it or is this hopeless?

user123383: This depends on the char set you used for your password. The numbers below are from Wikipedia (no guarantee) and describe how long it takes to crack a password with a standard PC + GPU. They are for the case that the password exactly 8 characters.
[0-9]: 100 ms
[a-z]: 4 min
[A–Z; a–z; 0–9]: 3 days
[A–Z; a–z; 0–9] + Special Characters: 84 days
So in the case of 8 characters there is a certain chance that you can crack it. However, if you only used a 9 characters pw, the last two cases already way more difficult.
[A–Z; a–z; 0–9]: 159 days
[A–Z; a–z; 0–9] + Special Characters: 22 years.
So for passwords with special characters 8 is the maximum length you have a chance. If the password only contains [0-9] or [a-z] there is a chance until 11-12 chars.
