Why is it taking so long to mine a single block. Like last hour only 2 blocks have been mined. Currently been 45 min since the last block was mined.
According to blockchair
Hour Blocks
5 *****
6 ******
7 ******
8 *****
9 ********
10 ***
11 ****
12 **
13 **
What could make 45 minutes go by without a single block being mined and having so many unconfirmed transactions still?
