I've been reading through this forums for the past few weeks and all I see is "this coin is dead" or "everything is a shit coin". Is there any alt coin with potential to invest in or is it only bitcoin?
Buy XRP that is not shitcoin , But your life will become shit once the cases against SEC losing 
But seriously that's a cheap buy now if you are willing to Keep a hold for at least year or more.
Remember that this is one of the most used coins recently until the case was filed.
