Two years ago I started a crypto trader based on machine learning (working fulltime since june 2018 on it).
By the end of 2019, I had a decent prototype with good live results.
In march of 2020, a guy (B) I met on reddit algotrading joined me. He was convinced to come flatshare with me and work on this together fulltime. He dropped out of school for this. At the time, he was doing his own algotrading project, but his project wasn't as promising, and he didn't like school, so he joined my project.
In April of 2020, another friend (C) started working part time on the project, doing mostly data engineering for taxes, and working with accountants to handle taxes. He doesn't have as much ML expertise as the rest of the team, but he still is a good coder.
In July of 2020, another friend (D) joined the project full time to work on ML algos and data engineering.
Everyone put in about 10k of his own money when he joined. Our activity has grown a lot and is now making around 2% of one of the biggest crypo-exchange's volume.
We are now incorporating a company. We plan to do a 4 year vesting schedule.
What do you think would be a fair equity split should be given the situation I just described?
