Questions people actually ask
The same things a relative asks before they tap the link.
Your registration link. When they open it, your member ID is already filled in, and the 3×3 group gives them the next open seat.
You have 24 hours. The panel shows a countdown with the name and the USD amount, so you can send it when you get a minute, before the window closes.
Help is in US dollars. Keep a USD wallet on the account, and a UPI ID if that is how you receive money at home.
