Why do people buy $10 stuff with Bitcoin? For what stuff? That doesn't make sense because they have to pay $30. The last time I sent Bitcoin for $30, it only cost around $1.5, which made sense to me.

Yesterday's incident of increasing transaction fees came suddenly and took a lot of people by surprise but it didn't last long. And now the transaction fees have dropped dramatically and you don't have to pay too much.

The important thing is that if you don't mind paying the transaction fee using Bitcoin, you don't have to. There is no compulsion you have to use Bitcoin and there are other cheap coins.
