1 bitcoin is now worth just under $2,500 USD. The currency is most certainly in a bubble, but the long-term prospects seem "interesting" to say the least. At this point, it could go either way. You could either make a fortune or lose your shirt. Why? Because bitcoin has some fundamental flaws, particularly the growing size of the blockchain. Even the designers don't know how to resolve some of the problems and some of the solutions proposed would "centralize" the currency, taking away the very thing that is making it attractive to many people--the fact that in its current form, it is a decentralized currency.
