To start, get a trizip, mk 3 vest, and buy a shit ton of ifaks and put them everywhere so theres no space. Also buy 1 water bottle, then go into woods night or shoreline night but I like woods more. Kill a scav or player and loot their body so you don't get a run through. Next, go to the nearest extract and sit in a bush and turn on the speedhack and turn it up to 10. Watch as your hydration goes down, then as it hits 0 start medding like crazy, don't be too slow or you will die. Once you run out of meds, drink water, and extract. You generally get around 30-35k for this method, but I used salewas so the number could be higher if you use ifaks.
