Stellar lumens

I invested in Stellar (XLM). While they're currently dropping, they are still well above the $0.20 average from only a month ago, and most alt coins have been dropping / leveling out after the crazy increases that everyone knew was not sustainable through the end of December.

If you're looking for a longer term crypto investment (i.e. more than 6 months), I think they are a safe bet. I see them maybe dropping down to $0.50-$0.60, then will slowly rise through the end of 2018. They have good backing as a company and should have no problem getting back over $1 and beyond.

I wouldn't put all $500 into XLM though. Maybe split half of it up and drop it into Ripple (XRP). They are both solid alt coins in my opinion.
