Hello my bitcoin brethren!

I come to you with a cunundrum today. One that's been weighing on me heavy for the past week.

Is it a good time to buy bitcoin, for a not too long term investment? And not just a couple of bucks but rather with a sum that would definitely sting (but not cripple) if the pendulum swings the wrong way.

I know your guess it as good as mine and the whole don't put in more than you are willing to lose and bitcoin is the least predictable investment venue...but perhaps you might know something I don't, especially consider how sharply it's been going up lately.
Some I realized don't like sharing what they know if they have juicy insight that they feel will change the course of things unfavorably for them if that knowledge was made public. If you are one of them, maybe you can PM me? 1 person won't make a difference.

So yeah, looking for expert, honest, advice.

Thanks!
