What are you finding that works to getting the most rewards? I like having 2 or more sentinels with me because I hate dropping connection when approaching a high traffic/populated area.
Do you let COIN mine while you sleep?
Where are you placing sentinels?
What about mailing an envelope to a friend with a sentinel inside with e return mailer back to you via cheapest postage rate. Curious what you can collect on that route.
I’ve taken public rail and Amtrak recently and got some surprising 16.00+ coin rewards (along with some sub 1.00 rewards :).
