I've no idea why we have to pay more for low performance. here's 2 examples.
Twitch doing 2 experiments, 1st Direct cheers and 2nd elevated chat.
If I cheer $1 on a streamer, I can give 3 users to (temp) emotes. BUT If I cheer with $5, there's only 10 users going to get it.
$1 = 3, $5 = 10, $10 = 15, $50 = 20, $100 = 30 users.
If I want to give more emotes, I have to pay $1 a lot lol ($1x10 = same as $100)
2nd elevated chat is also worst :(
here's Amount / Duration
$5 = 30s, $10 = 1m, $25 = 1.5m, $50 = 2m, $100 = 2.5m
Yes, I want my chat message longer! I'm gonna pay $100 for 2.5m XD
...seriously?
Even I can't change my message, its just same as $5 x 5 that I can send all different message, but same duration.

I know ' Experiment ' meaning ' Trying '
but who wants pay more money even that is not that helpful to others.
some? or many people feel annoying to pay lots of times, so they just gonna pay $100s. (...I bet some)

:( just weird
