Did that at 1u yesterday. Quickly park a pidgeot in there and claim free 10pokecoins.

If you are quick enough to hijack 2 gyms like one world hotel or center point bu. then can get 20 coins.

Hijacking even low level player can do. Just have to be quick.

21 hour thingy if you can defend the gym

I have no idea on this.

you try first see how and tell us ok?

Cheers!

Easier way to think of it is that you can only press that shield button every 21 hrs.

If you haven't press that button and you slot in a Pokemon into the gym. Straight away go press it. 10 coins.

Botters are now become smarter, they will keep develop a humanized botters. They are now already figure out niantic was limited to catch 1000 pokemon and 2000 pokestops per day. Soon they have more things to analyse and become much more smarter than niantic. Now pokemon go bots are able to change random walking speed. Someone replied me here, he says bot will continue to develop but need to pay. Absolutely is wrong, you know? Necrobot the latest version now is 0.9.0 just most legit players still don't know about the truth. Necro developer was official announce to stop but there have some others developers to take over their bot to continue update to the latest version, now already update to version 0.9.0.

Since bot can always catch every pokemon at the maximum of 210xp, now there have bot function to randomize the XP for every pokemon catches. They can either set to catch every pokemon at 210xp or set to 100% catch 110xp this is up to their config settings.

Niantic just ban everyone including innocent legit players. My advise is please don't connect to public wifi or your friends house wifi during you play pokemon go. Just keep connect with your own 3G/4G. Some legit players get banned is because they connect their pokemon go in the same IP with botters.

And also, please do not using NOX. NOX is even more dangerous than Pokemon GO bots. Bots have config to set the phone ID and bootloader, to make it pretend as a real phone. However, nox is just a virtual android software. Niantic will immediately detect then perma ban.
