Personally, I'm not very interested in the Bitcoin project, so I gave it a score of 2.
Bitcoin has reached its current popularity and value just because it is the first cryptocurrency. I can boldly say that 90% of other blockchains have better features and quality compared to Bitcoin.
Bitcoin is so slow that I once waited 3 days for the transaction to reach its destination.
Fees are high, especially when the network is crowded and the low number of coins makes it difficult to calculate and the numbers can not be easily expressed. For example, when I want to send dogecoin, I say I want to send about 2000 doge coins, but there are no interesting numbers at all for bitcoins in low amounts.
In the screenshots below you can see the unapproved transactions and the time of sending them, and this is enough to realize the speed of sending and receiving bitcoins.
