RE: Koinos Club v2.0

Great work!

I tried using it, but got some errors:

(I fixed this by editing app.js)

[JS] uncaughtException: spawn /root/koinos-miner/bin/koinos_miner ENOENT

    console.log(`[JS](app.js) Error: `, error)
                                        ^

And after that, I received this error.
