I am not sure if it is the best place, but I receive many emails with question about my WifSolverCuda - NO, it cannot be used for finding 32BTC puzzle coins. Converting puzzle into WIF with missing end is not a good idea, it will not work! Apart of fact that it is one more layer added, my program is developed for WIFs with missing end/middle.
The same with CPU version WifSolver. So please, do not ask me about it anymore 

Just to add something to the list - one may check my patched version of Kangaroo, where one may test given range with a stride, so for example check only even or odd keys.
