mining-dutch.nl - auto profit switching for most profitable Scrypt coin for your L3+'s, and you can auto-convert to any coin you want to hodl, even cross-algo like mine Scrypt coins but convert to and get paid in BWK (nist5)

current servers in Europe and Asia - and soon North America (although I currently mine there from the US to EU server and it works fine)

Blake2s, keccak, Lyra2REv2, myr-gro, neoscrypt, nist5, quark, qubit, SHA256, skein, X11, and X11gost algos also supported.

For my L3+ and L3++'s I use:

URL:        scrypt.mining-dutch.nl:8888
worker:    MDusername.workername
password: d=65536

"d=65536" in password field sets the difficulty, all this is explained in their "getting started" page of the mining-dutch.nl website, and there is an active Discord server for support and general chit-chat with fellow miners.
