This is a great chance to put the resilience of the btc mining system to the test.

Since there is a huge backlog, that means TX fees are going way up. If TX fees are going way up, that means the profitability of mining is also going up. If mining becomes more profitable, then we SHOULD start to see the number of miners and hashrate go up as well, until it evens out to the point where mining becomes just barely profitable enough again.

Let's hope that this theory holds true in this situation. The increase of txs will not be a problem if we also gain an increase of mining power in proportion to that.
