The one you described is a win win situation so seems like the best choice for you.
This is not something I would recommend to anyone doing profit now in this bull market like last months some people may get fooled into thinking they are great traders, but not your case as your profit comes from arbitrages and it shouldn't matter bull or bear situation.
I like your "scientific" approach to what you are doing and am curious about your studies background and the job you quitted was somewhat related to this new path or was something totally unrelated.
Yup same way people were fooled in 2016 and 2017, thinking they were amazing traders and investors. Made money from every strategy and every ICO, and some people thought bounty hunting was going to be their life profession.
Read research about traders and how majority lose money.
Arbitrage is tricky too and can bite you.
