FISH
https://en.wikipedia.org/wiki/FISH_(cipher)
The FISH (FIbonacci SHrinking) stream cipher is a fast software based stream cipher using Lagged Fibonacci generators, plus a concept from the shrinking generator cipher. It was published by Siemens in 1993. FISH is quite fast in software and has a huge key length. However, in the same paper where he proposed Pike, Ross Anderson showed that FISH can be broken with just a few thousand bits of known plaintext.

I disagree, I always thought it was FISH.

Definitely not Twofish, that's a different one.

Wait, Seimans made a cipher? That's surprising!

Nope, it's actually Blowfish!

I think that's RC4, right?

I feel like FISH could be a trick option, but I really can't recall the specifics about it.

I practiced a similar question on stream ciphers last week, and I think RC4 was the answer there too.

The mention of Lagged Fibonacci makes me lean towards RC4, but I could be mixing it up with another cipher.

I think I remember studying about stream ciphers, but I'm not sure if it was RC4 or something else.

This looks like a complex question with a lot of moving parts. I'll need to carefully read through the details and think through the different patterns that could be applied to solve the data exchange issues.

This seems straightforward - I'm pretty sure the answer is compound interest, since that's the standard formula for calculating interest earned over time.
