The crypto bonus sounds like WinterMute and yeah that's correct. You are supposed to share the full amount of earning, even potential earning. Offer letters have bonuses stated in them right?

I've never heard of any company not stating how much bonus you will get. All the places I've worked at either stated minimum value or what percentage of base pay I will get annually.

Take base pay + sign-on bonus / allowance + yearly vesting stock + average of that bonus or the full amount of it = TC...
