Don't spend bitcoin for trading,spend it as money that is what I tried to say.If we keep using bitcoin only as trading purpose then it will never become a main stream payment.
The question I'm always asking people with opinions similar to yours is: Why would I spend Bitcoin that appreciates in value and not fiat that depreciates?
I have fiat and Bitcoin, every month I earn fiat and Bitcoin. Fiat at work, bitcoin through a sig campaign. Why would I hold my fiat and spend Bitcoin? This is just unreasonable to me. I've been doing the opposite for years now and it's been great for me.
