First of all, don't take investment advice from random people on the internet...
My personal thoughts on bitcoin is that it has huge potential when it comes to commerce, sending money across borders and micro payments. That being said, there is still a lot of infighting within the community when it comes to upgrading the technology, which I personally think is necessary to really take advantage of bitcoin's potential. If the bitcoin community can't find a way to upgrade the tech, I fear it will stagnate and another cryptocurrency will take the lead.
I won't get too much into all the details unless people are really interested...
