understanding conversion?

i bought 150 of some coin at 59 cents.

currents its down 4 cents and ive lost $5 in response.

this is way more of a change than i was expecting even in the positive region.

i was assuming either way it would be pennies and dimes. I,e. if the coin goes up to 1 dollar i would now have 150$ from my 90ish invested. but this is seemingly way more influential. am i missing something?

4 cents downs and i lost 5 bucks? but if it went to 80c would i be up 40ish dollars..?

im sorry if this is confusing im a little tipsy but am trying to figure out my finances a little more. any input would be greatly appreciated.
