Hello Team. Some tips below. Probably known by the more experienced but may be helpful to beginners.

Save your lucky egg for a mass evolve. Collect a whole bunch of candies for the cheapo pokemons like Pidgey, Rattata and Caterpie. Then break out a lucky egg for double XP. Lucky egg is active for 30 mins or 1800 secs. If you're real fast, say, 25 seconds for each evolve, you can evolve 72 pokemons for 72000 points.

Legitimate fake location If you're indoors at home, check to see if there's any difference in your location when your wifi is off and on. If there is, toggle your wifi every few minutes. That'll get you moving a little bit. It's not much but I find it good for hatching those 1.9/2.0km eggs.

Pokestop No. 10 If you spin 10 different pokestops. The 10th one will give you double XP and more items. Not sure but there may be a time frame of 30 mins in which you have to go through all the 10 pokestops.

Gym Pokecoins If you managed to put a pokemon into a gym, immediately, go and collect your 10 pokecoins. Many beginners seem to miss this.

Hatching Eggs Hatch your 2km eggs first. Delay as much as possible until your level is higher before you start hatching your 5km and 10km eggs.
