so, not sure if it's a glitch or intentional, but after buying "the point" enough the cost starts to become seemingly random, even turning negative sometime. eventually after it got to somewhere in the 200's, it became just free. I'm going to keep going now and see what happens.
Update: It was a mistake to chase this path. I was tempted by the possibility to reach an immeasurable growth rate, but now I am left without anything. Even when the cracks started forming. as the numbers grew to be negative I kept clawing. I saw that despite what it said the amount I had still continued a steady rise. I kept going believing that just over the hill, I may find that which I seek. As I finally stumble down the other side I see only the barren fields of my greed and stubbornness. While it may continue growing, it is only in it's monotonous, slow, creep.

Anyways! In simpler terms, I continued getting "the point" in it's free state, eventually however, I think it kind of broke the game. The $/S became negative (I forget at which number specifically) despite this I was still earning money, albeit at a slower rate. I continued to buy "the point" since as I continued the negative number got smaller. eventually I managed to get it all the way down, but then the $/S just disappeared and it doesn't seem like the rate at which I'm gaining increases when I buy other things. Currently "the point" is at 6503. Take my advice, though the glitch seems tempting don't keep buying "the point" when it costs money.
