[questions] External&Internal, overwatch

1.What is the difference between external and internal in cheats, and where to learn ?
2.Apparently there Overwatch bypass, in the form of the program, the Ruthenian forums, it is true?
3. Is online program that buys the cheapest eg scythe on the market, and sell more expensive ?

Internal
==============
Pros:
+ Fast
+ Easier to read memory (typing wise)
+ Can hook and call game functions much easier.
+ Very fun to work with (IMO)
Cons:
- Debugging logic errors takes a while
- Have to inject

External
==============
Pros:
+ Easy to debug and test a lot
+ Full control over your application
+ Can be done in many creative ways
+ Your bad code won't fuck the game
Cons:
- Slow(er than internals)
- Harder to read memory (typing wise)
- Less fun (IMO)



The only overwatch "Bypass" is not really discussed so hopefully nothing will be patched, PM me on skype for more information on the bypass.
