Trump announced WLFI.  What's this all about?

How do you make money on transactions with a bitcoin node?  I saw somewhere this was possible with a lightning node.  Maybe there are other ways?  I tried installing the Electrum wallet, but it never earned a profit.

Is there some type of graphical interface I use to mine with my antminer u2s?  Looking for something quick and easy to get them mining.

I guess I could run a miner off my dryer plug, but looking for the most efficient 120 volt miner.  Not sure what that might be?

I would probably mine continuously if I had a place to keep the miners cool.  For the last 3 years I have bought a miner in the fall and sold it at the end of winter.  I basically use it for supplemental heat and a lottery ticket for solo mining.  What type of miner should I invest in?  I lean towards trying to obtain an S9.  Last winter I had a S7.  I sold it for almost the same price I paid.  I am aware that a number of alt coin miners are also available.  My goal is to lose as little as possible when I resell the miner in 4 months.  Where should I obtain the miner and what should I be considering?  I have been keeping my eye out for GPUs, but it doesn't seem like something that is easy to get.  I recently replaced the GPU on my PC and purchased a 1060 3gb model because the price is right.  Apparently it hashes at 15mh with my attempt at mining with it.  I need it to work for my PC so I don't care to mine with that full time.  The deal I got I was only able to get one for $175.  My electric rate in the winter time is 4-5 cents a KW/h.

Someone hacked my account.  Not sure what for, but their first post occurred on the 16th of July.  Original handle was "truckinusa."  Kinda aggravating.  What do I need to do?
