Not every answer can be easily found by Googling.
Some questions are about a deeper level of understanding.
For example, I’m not 100% sure how do blockchain updates work. For example, if my ETH is in a cold wallet with no internet connection, how will it get the update?
Or do only the nodes need to get the updates?
Now I understand this could be a stupid question coming from a lack knowledge, but I really want to understand the technology more.
What are things you want to know but too afraid to ask about crypto?
