Bitcoin isn't just first mover:
No one is even trying to compete with its functionality.
This functionality being maximum security in the form of 10 minute POW blocks.
No other network even attempts to compete with that.
- There are no 20 minute block tokens.
- There are no 10 minute block tokens.
- There are no 5 minute block tokens.
- Lowest I've seen is 2.5 min (Monero and Litecoin, etc.)
Bitcoin clones don't count because they use the same hashing algo SHA256, making them extremely vulnerable.
Because it takes so long to mine a block and blocks are so tiny, this also means that a Bitcoin node is cheaper to run than any other kind of node, again making Bitcoin's main strength security and decentralization. There is zero competition; the entire market is cornered by Bitcoin's small niche. Good thing there are 1000 other markets to corner.
I had not even thought about block length when looking at targeting markets. Really interesting viewpoint as you are absolutely right regarding the affordability of running the nodes.
