Whenever I have to introduce the concept of fees and how they work in a transaction to someone, I always opt to use mempool.space as a reference due to the amount of information that it provides and, most importantly, how easy it is to read the information being displayed there.
Just this morning I was trying to explain to a close relative how my transaction was stuck in the network for 2 days, he doesn't know much about Bitcoin so it was difficult for him to understand, so I used mempool.space to explain everything to him and he understood the whole thing pretty quicker than I expected.
I actually haven't used many explorers like that, but I don't bother because of Mempool.space gives me all I need. Before I make any transactions, I usually check the fees there first so I'll know my next move.
I assume that most will just avoid buying Bitcoin but the worst part of it is the damage that it does to the overall adoption of it.
I have often said that high network fees are a bigger problem for Bitcoin adoption than we think. What is the point of Bitcoin having these unique features if I can make a transfer and get it confirmed within minutes? Why do I have to wait an hour, or even days in some cases for a transaction to be confirmed or pay a huge fee if I want it done quicker?
These are the kinds of questions people would ask and these kinds of questions hinder adoption.
Adoption to me is not just the amount of people who own or use Bitcoin, but also being able to use Bitcoin anywhere and anytime.
On the issue of network fees, last I checked it was around 53sat/vb, that's about $5. It's still relatively high, but if you consider the fact that 3 days ago it has gone up to about $50, I believe it's coming down now. Hopefully, it continues at this rate.
The problem is, there will be more congestion in future.
