There is a small group who seem really good at spreading a message of "Bitcoin is about to collapse". They are doing this either because they control a lot of competing currency (Ethereum), or because they think it will help adoption of their Bitcoin fork.

The reality is, 95% of Bitcoiners are very happy with the team working on the protocol, and the market seems happy too (the price has gone up +68% over the last 6 months.)

But you absolutely should not take some random internet person's word for it. You'll have to invest large amounts of time reading bitcointalk, reddit and the like to make a sound decision. Luckily it's pretty fascinating reading. In time when Bitcoin's future is clearer, it will either be worth much more, or nearly nothing. But I think you can get great insight into where it is going by following it closely today.
