Yes it can make you some money.  Will it repay itself at this point?  No one has any clue.  Right now you will earn between $45-$70 USD per day (a huge range) and it is only going to go down.   If you pay $4,500 USD, you MAY have a 100 day ROI, it may be a year, it may never if the coins fork.

You have to make your own choices.  I bought one when it first came out because I thought the risk was worth to potential reward and I have earned about $1,000 back.  I still have a ways to go.
