Is there a budget system here? and Is there a way to know where these coins are going too like which project? (talking about the donations and MoneroDice 10% funds)
Most of the funding (crowdfunding/donations) is now via the Forum Funding System, where you can see which projects were funded under Work In Progress and Completed Tasks (in the Archive section). New proposals are in Funding Required. All of those are here: https://forum.getmonero.org
The direct donations to the project were used for some freelance developers, crypto review, etc. last year along with ongoing things like hosting, legal, etc. That had some accounting posted a while back, where the amount donated ended up being well short of the amount actually spent, with the remainder covered by the core team itself. Since the development is now primarily funded by the FFS above, direct donations have tapered off but donations for covering project overhead are still welcome.
The MoneroDice 10% funds don't exist yet as at least two people have explained, but if and when they do exist they will probably go through the FFS. That's up to fluffypony though.
I love the transparency of the Monero team.
Profitability for the dice site will come in the long term. In the short term, normal variance (and a low house edge) can lead to unpredictable results.
