Bitcoin will never be used for trading. Why?
- Extremely slow transactions
- High fees
- Inability to solve these issues due to lack of consensus, poor governance, and a generally toxic relationship between investors and the technology
Now I could be wrong, and I would gladly accept that I am wrong if someone could give me clear, coherent, and rational reason for utilizing bitcoin as a actual cryptocurrency and not a cryptocommodity.
Disclaimer: I have nothing against Bitcoin. I just don't think it's future is bright anymore as way better technology is coming into fruition.
If by trading you mean as a payment system, lightning network will reduce both fees and transaction times. There is alot of innovation in regards to BTC right now.
If by trading you mean like Forex trading, once price fluctuations stabilise, this will be a thing.
If by trading you mean used a a base currency to trade alts - this is a thing.
