How does a hashing algorithm work?

Could I reasonably attempt to brute force the password to an old TrueCrypt volume of mine?

I had $20-30 worth of bitcoin back in 2013 when mining first exploded, where the price was about $1000 per Bitcoin. So, given the recent explosion in Bitcoin price it got me thinking about trying to find my old Bitcoin wallet and see if it has anything left in it. I found my old hard drive and plugged it into my computer to copy the files over. While I had labeled the drive "ALMOST DEAD" and it regularly made clicking sounds while plugged in, I managed to copy over my Documents folder from it. On there I found my Bitcoin folder, with a 16GB copy of the blockchain (oh, how times have changed...) and a "wallet.dat" file. Awesome! Trying to import it into BitPay brought me to a new issue; I don't remember the password! I tried all of the possibilities that came to my head, and none of them seemed to work.
I poked around a little folder in my old files and found an encrypted TrueCrypt volume. At the time I did like to save my important passwords that I couldn't change in text files, and store those in a TC volume. So there's a reasonable chance that volume contains my wallet decryption password.
So here's my question; would it be futile to set my computer loose on that volume and try to brute force the password? My knowledge of security at the time wasn't great so I think it's reasonably likely that the volume was encrypted with an 8 character password, maybe a 10 character password, that was just alphanumeric. I know that for cracking an MD5 hash that would be a hilariously easy crack, but for a proper hashing strategy, like bcrypt with a cost of 12, that becomes a serious issue very quickly, because calculating one hash takes a long time. I don't know whether there is a "hash" function to calculate for trying a password on a TC volume. The volume is 100MB; how long would it take to try one password on that? My computer has a GTX 1070 and i7-6700k with 16GB of RAM; does that help me here? If I can, what tool would I use to automatically try all of the combinations, or is there a simple script I should write?
Also, would it be better to try to crack the password to the Bitcoin wallet directly? I'm assuming not.
TL;DR: Cracking a 100MB TrueCrypt volume, with a GTX 1070, i7-6700k, and 16GB of RAM, most likely a 8-10 character alphanumeric password. Can I do this? If so, what tool/scripts should I use to implement it?

Hash functions are related to (and often confused with) checksums, check digits, fingerprints, randomization functions, error-correcting codes, and cryptographic. Although these concepts overlap to some extent, each has its own uses and requirements, designed and optimized differently. The Hash Keeper database maintained by the American National Drug Intelligence Center, for instance, is more ... Hashing algorithms are an important weapon in any cryptographers toolbox. They are everywhere on the internet, mostly used to secure passwords, but also make up an integral part of most crypto currencies such as Bitcoin and Litecoin. The main features of a hashing algorithm are that they are a one way function – or in other words you can get the output from the input but you can’t get the ... BLAKE and BLAKE2 are cryptographic hash functions based on Dan Bernstein's ChaCha stream cipher, but a permuted copy of the input block, XORed with some round constants, is added before each ChaCha round. Like SHA-2, there are two variants differing in the word size.ChaCha operates on a 4×4 array of words. BLAKE repeatedly combines an 8-word hash value with 16 message words, truncating the ... The question is how long should a hash take to compute. At the time of deployment in 1976, crypt could hash fewer than 4 passwords per second. (250 ms per password) In 1977, on a VAX-11/780, crypt (MD5) could be evaluated about 3.6 times per second. (277 ms per password) You should be adjusting your bcrypt work factor so it takes 250-500 ms to ... Online Hash Calculator lets you calculate the cryptographic hash value of a string or file.
