I've been reminded by Skink that there's one other important piece of information from the discord: Rune/Savo confirmed that you do get paid for scanning other starters. Scan rewards are the same as catching rewards, (scanning rewards being half of scanning+catching rewards) so people who start with a 1k starter would have 9.5k after scanning all the other starters, and people who start with a 2k starter such as Tilly would have 10k afterward.
