OK, I don't totally understand that, but your comments educated me a little bit and I appreciate it. For other coins, I'm not sure there's an option to download an ARM format, but maybe I'll take a look around at some wallet sites and see.
Technically you don't need to have an arm distribution of the software, if compiling from source, just install the dependencies necessary (which will be in the source code and can be found in the readme normally).
Compiling from source, especially with the low memory of the pi1 and 2 in my experience has just made the compiler give up.. But there are commands you can use to avoid this...
Perhaps, if there aren't any arm builds of the node software, you could open an issue on github to ask for them to compile one, if you can compile for 8086 or 8664, you can compile on arm just as easily unless there's any asm as that needs translating... (arm is better than Intel and amd).
