For each transaction, I am charged 0.0001 bitcoin. And when the bitcoin value is only about $ 1000, it's very simple. However, bitcoin has reached $ 20,000. And each time my transaction cost more than $ 10, really difficult
This is only due to the fact that the Bitcoin price increased drastically and the difficulity of mining didn't follow along with it. This will happen at some point, as more and more miners will want to get involved with Bitcoin as they want to make some good money as the difficiulity is low - which will balance out at some point, brining the TX down with it.
So, this is a temp thing and will be corrected-- don't get too worried YET.
