tracking bits usage
A screen that every account would have that shows bits spent in the last 30 days (or longer), this would enable everyone to see if their account has been hacked, and being used to bit farm for a channel they do not actually watch.
I don't know why this hasn't already been implemented, but I think it is crucial that we are able to see our cheering history on Twitch. While I understand that if someone was to purchase something like V-bucks on the epic store and use it to buy a skin on Fortnite, you wouldn't necessarily have a transaction history telling you when you purchased things and for how much, but it is definitely a feature that should be added.
The striking difference that I see between buying something like v-bucks on Fortnite and buying bits with which we can cheer is that when we spend V-bucks on items, we are paying for a material item. Maybe it's not something that we can hold or touch, but it's a virtual thing that I can see that I've bought. Through looking at that, I can deduce how many V-bucks I've spent since skin prices remain relatively constant.
There is no such luxury on Twitch. If someone hacks my account and buys hundreds of thousands of bits with my credit card, it would be nice to know where those bits went.
In addition for the need to have a bits transaction history for security measures, it would also be a nice feature to add. I know that Streamlabs added a feature a little over a year ago which implemented not only a transaction history of every donation we've made through the platform, but also, every time we donate, Streamlabs clips it so that not only do we have a written record of it, but we can relive the moment as often as we want (provided a streamer doesn't decide to delete all clips as quite a few people have done recently due to all of the DMCA stuff happening.
If this feature does ever get developed, it would be nice to have past cheers available as well so that we can see our complete cheering history and not just cheers that we have made after the feature was developed. When streamlabs came out with their new feature, it included the donations I had made going back to my very first. Obviously, clips were only made after the feature was developed, but just having the history is the important part here.
