Oi Lucas! Como voçê esta? I'd be glad to help

usually it's referred to as pool/money pool...in other words you could probably call it as: Collection...not ideal but that's the action here anyway..

Yeah as Chris mentioned, the sentence is formed correctly. it's just the punctuation mark that gives the finishing touch

hey welcome mate! I think you are referring to the video from that girl(i keep forgetting her name, apologies). Anyhow, it would be a pleasure helping you with British English/accent. I could may be get a little better in Mandarin. Well..feel free to reach out Cheers!
