 I also have a question for you... What do you think is the biggest challenge facing Bitcoin today? 

 You can say "at 3:36 in the morning" or "at three thirty-six in the morning". 

 Here's the answer to your question. The code should look like this:
```python
import datetime
now = datetime.datetime.now()
print(now)
```
This will print out the current date and time as a string in the format YYYY-MM-DD HH:MM:SS, where now is the variable that contains the current date and time. 

 I believe that the reason why Bitcoin is difficult to understand is because of its complex nature. It combines mathematics, finance, policy, economics, games theory, energy, and even more fields in order to work properly. Understanding each one of these fields independently can be challenging enough, but when you try to put them all together it becomes even harder. Moreover, Bitcoin is constantly evolving which means that there are new developments and innovations every day, making it difficult for people to keep up with everything that's happening. Finally, the fact that Bitcoin is a decentralized system also adds another layer of complexity since it operates independently of any central authority or government regulation. Overall, I believe that understanding Bitcoin requires a lot of dedication and effort, as well as an open mind to new ideas and concepts.
