Bitcoin is not developed enough to be a real currency. As others have stated, it is more of a commodity.
Because of it's volatile nature, it is very very risky to use to as a major currency because something that costs $5 today might cost like $10, $20 even tomorrow.
On top of that, the general public who have no technical knowledge wont be able to use bitcoin unless more people get into development and more elegant and user friendly solutions are developed.
Everybody is still waiting for the killer app of Bitcoin. It will take some time.
Bitcoin is great for cross border remittances, but not very user friendly. And the high transaction fees are more or less killing microtransactions.
Man, I forgot about the fees, don't even get me started! It used to be OK to send tiny amounts with low fees (cleaning dust) and actually expect them to confirm..Things hang so perilously in the mempool now, it's a crap shoot no matter how.much fee you attach. I simply expect a ten percent tax on my bitcoin purchases at this point. For once, fiat is looking way more attractive to hold asy 'housr' currency.
Bitcoin is about to hit a lurch, I can taste it. Too much bull in the air ATM
Why do we always hit an ATH, then the world crashes and burns around us?
