There's only one that's even marginally good for compiled (non-interpreted languages), and that's Hex-Rays:

That being said, you can't recompile what you decompile, so it only will give you is slightly more insight into what they're doing... You're better off just getting a disassembler and working in assembly - it will completely work, and you can do whatever you want, but it's also much more difficult.

This is very true, reversing most compiled languages such as c and c++ is very difficult. The software on bitcoin miners is mostly written in c with scripts controlling execution and configuration.

Last time I looked at it HexRays was not ready for production use. With trained eyes, disassembler and debugger it's possible to locate algorithm inside a program and make usable C sketch of it, but it takes A LOT of time, think ~3 full days for 100 lines of C code.

I'm looking for a good decompiler for software that doesn't provide source code.

Which software in particular? Its hard to help without knowing specifically what you are trying to decompile and why.
