Hi,

I have recently been trying to build a backtester/strategies to trade cryptocurrency.

How do we go about portfolio management compared to equities since not everything has the same numeraire?

Do we take all pairs and calculate prices for every traded currency in terms of one currency (say USD) and then proceed like how we would in equities? e.g. calculate optimal portfolio, risk, etc.

But then how do we rank based on previous day’s dollar volume? do we only use the most liquid path from an asset to USD? or do we aggregate across all possible paths to USD?

When trying to forecast future returns of our assets, do we only use the shortest series of hops? or do we also use information from the intermediate steps? e.g modeling ETHUSD (which is traded on exchange), do we use ETHUSD or (ETHBTC x BTCUSD)?

Hi,

TL;DR: Having more and more frequent binges after extended caloric deficit and trying to eat slightly more/resisting the binges isn’t working, what do I do?

28M 6’ I started at about ~230lbs at my heaviest multiple months ago and was able to get down to around 173lbs at my lowest measured weight about a month or so ago

My goal weight is around 170lbs, but I have been really struggling with binging episodes as of the last month or two. I am able to stick to my ~300 calorie deficit with difficulty, but it’s been feeling more and more like I don’t have a say in it because my body takes over and makes me binge after I start eating. This happens no matter much fat/protein/fiber/fruits/etc. that I try to eat.

I’ve gotten pretty distressed from watching my weight increase moderately quickly (~185lbs rn, I know that a good amount of this water weight, etc. but still) and I feel like I’m undoing all my work and have little control over it when the hunger takes over.

I do see mental health professionals for BDD among other things and am trying to get in to see a registered dietitian.

I have gotten good advice to try and go back to maintenance calories for a bit, but I struggle to even do that without just blowing past maintenance during the binges.

The binges have become more and more frequent and I don’t know if I should “honor” this urge to eat a lot with the goal to show my body that it doesn’t need to be in survival mode thus reducing the extreme hunger or really push back since resisting seems to make the urges stronger and stronger, but honoring it by following the hunger makes me feel like I’m undoing everything :/

But yah, do y’all have any advice on this?

Thanks :)
