Investing in new technology can be frustrating no matter the amount of research you do, don't let anyone tell you differently. At the end of the day investing is a risk, and no one can tell you (outside of price manipulation) what anything will cost tomorrow, even USD can collapse. All I can say is, if your interested enough in investing but are hesitant, dollar cost avg over a long haul. That way you don't buy the top but you won't buy the bottoms either (assuming the price does not go to zero, which is always possible with anything) - but be prepared to be on an emotional roller coaster, if you can't handle the swings it's not worth it.
