Indeed, if the price fall back to the point of 100$ per 1 bitcoin, that would be a good investment. Because the potential of this currency in a current period really unpredictable, but if it goes down even to 300$, I should say it's still improbably really profit investment
I totally agree with what you are saying. And it would be great invest if it drops back to 100$ and the rise back to what it is today.
But personally I don't think that something like that will happen nowadays. Because things keep getting better and the price keeps on rising.
