Making a million with Bitcoins today is probably still possible, but you will need some capital. Bitcoins can fluctuate many percentage points every day. Day trading Bitcoins is going to be risky, but where is there is volatility there is opportunity. Otherwise, you need to take a longer-term approach and conclude whether or not you think Bitcoin will be successful. If you think Bitcoin is going to be traded by foreign exchange dealers, market makers and institutions one day, you might want to go long. Buying right now would be incredibly risky; the price chart is screaming “bubble”, but your point of entry is up to you. Don't expect to see more of the same fast growth now though.
