I think it's fairly obvious he is 100% on government support. Disability, welfare, foodstamps, housing aid, medicaid. His mom has openly admitted that the 3 of them were on government assistance and that was their only income for the time they lived together. In addition, we know Cosmo was on some form of government medical insurance a couple years ago because when he failed to fill out 1 simple form to renew it, it lapsed, and this is the excuse he gave for ordering black market hormone/tranny drugs. I do not believe for a minute he got some sort of huge windfall from crypto.
If he did, that just adds to what an abomination of a person he is, as his parents are still living in squalor due in very large part to being suffocated and held down by the $100k+ student loans that still exist from when they put him through art school in Chicago. According to his mom, his parents can't even afford a couch. All of the above context clues combined with the very plain / poor look of his new place in addition to the fact he doesn't have most of his stuff lead me to believe the crypto windfall thing is 100% bullshit. If he really spent $7-8K moving around in the past few months he would have absolutely had all of his stuff delivered to his new place.
