Lately I am reading few articles about Lightning Network. We know that for scalability, for cheaper transaction Lightning Network is a good solution. If I am not wrong then it is live in the Bitcoin mainnet.
Technically it's not on Bitcoin mainnet (except when you open/close channel), but you can use LN on Bitcoin mainnet today.
What I understand is that installing the Lightning Network is extremely hard however I am considering to install and test one to see how it goes.
There are plenty information/guide about LN, so i'm sure it's not extremely hard. You might want to check this thread

According to an article they made about $125 in a week on an investment of $2000 which was spreaded over 200 channels. It is around 5% a week which is not bad. They paid around $60 in transaction fees to setup all the nodes so they got it back in 3 to 4 days and after that all were profit. By the way that did not include the set up cost for nodes and the server cost. They had the Lightning Network with over 200 open channels. So far it sound very good to me.
Sounds bullshit to me, routing transaction fees on most LN nodes are very low (usually below 1 cents)
Making your nodes have hundred of channel isn't easy unless you're merchant, have big coin capacity or you're the one who connect to other nodes (which mean you spend transaction fees). Additionally, if you set fees for transaction routing high, LN client could route through another nodes which offer lower fees.
