Agree it's a great time to buy it. I am thinking of investing in it as a noob, to boost my SP. Any ideas how much I should buy? Like a hundred bucks worth will that make much difference?

It's totally linear. Twice the SP gives twice the upvote. If 70 SP has a $0.04 upvote, then 140 will give $0.08.

thank you, good to know. Is probably obvious but now I need to figure out how much upvote $ comes from how much SP

$100 adds about $0.01 to your 100% vote value. It adds up over time but it is pretty modest at first.

Saving up the SP you get from posting and commenting can also build up your power over time.

Nice, that's a good rule of thumb.

so it's hard to get much money, huh?

Invest as much as you are willing to lose.

As for your SP making a difference, I can tell that my 70 SP is worth around $0.04, so it really depends on how much of a difference you're aiming at.

I've been trying to find out how much give "maximum benefit". The approximately $100 worth of power I currently hold certainly makes a difference, but I'd be interested to hear from anyone who knows more details.

Invest amount that you could burn and not worry after twice or you will worry a lot.
