I remember I was playing with the first wallet and I said to myself, ok It must be very safe password, so its combination of some of my favourite passwords + numbers + special characters + upper lower characters and the length around +20
. It was logical back then but today 1-2 years later I have no chance, I even tried writing them on paper all my favourite words + number combinations + characters that can possibly fit into my stupid logic, but there are so many options
. I have now backup of my wallet and it will be probably a part of my last will. With Wall street expectation that BTC could reach 400 000$ in 2100, it might be a nice heritage for my descendants. Or I just need to wait for better computing power to come or any other solutions. I have cooled down a lot now, its not the end of the world and its not completely lost, maybe lost for me but still my descendants might find it useful
Keep writing down anything you think of:
Number of characters, possible words, special characters that you know you would NEVER use, special characters that you are likely to use.
All of this information will be helpful to your descendants when they hire someone to write a program that cycles through all possibilities. The more information you have about what is likely true and what is definitely false about the password, the more likely that a brute-force program will be successful.
You say it is "length around +20".
Can you say that it is definitely less than 100 characters? How about 50? 30? 25? 22?
Can you say that it is definitely more than 3 characters? How out 8? 12? 18?
Is it likely to be mostly lowercase with a few uppercase, or is it likely to be mostly uppercase with a few lowercase? Perhaps it's likely to be an even split?
It half of it special characters? 90% of it special characters?Only 1 or two special characters?
Is likely to be a single dictionary word? Two dictionary words?
Keep thinking, keep writing.
The more details you can think of the better the chance that it can be found someday.
