Yes, it is likely that YFI holders would incentivize themselves first. This is because they have a vested interest in the success of the YFI token, so they want to ensure that it performs well and provides them with a good return on their investment. Furthermore, YFI holders are likely to have a better understanding of the token and its potential than most other investors, so they are in a better position to make decisions about how to best incentivize themselves and increase the value of the token. This could include investing in projects that will increase the value of the token, participating in activities that will increase the visibility of the token, or simply holding onto the token for a longer period of time in order to benefit from its potential appreciation.
