For the next 7 days, Spaceship Voyager has doubled their referral bonus to $10 for both referrer and referee once a minimum $5 has been deposited by the referee.
I have no association with Spaceship Voyager, only that I’ve had a good experience using it so far.
Don’t forget to use a referral code (below) to claim your referral bonus.
[UPDATE]: You can also enter a referral code after you have signed up. Please follow the instructions below (thanks Atlinus!):
In mobile app:
Go to Account -> Referrals -> Enter Referral Code
Go to Account (bottom left) -> Referrals -> Click on "Click Here"
