Bitcoin is really the best and fast reliable for all my transactions. reason because it perfectly allows me to send and receive payments around the world, without even relying on so called traditional banking systems.
Not the fastest we have on the crypto catalog

but it gets the job done in good time

Bitcoin transactions payments are Quick and free, it helps your transaction to proceed very fast just that it may take a few minutes and cost a few dollars to proceed.
I believe this was a figure of speech to mean that when compared with fiat.. fees are peanuts when spending/sending out big money..nice word play, hope this was your intention

I see it as my number one choice because it gives perfect top security settings through the blockchain technology.
I don't know, I think this is debatable considering it relies on what security measures a user has put in, and what kind of wallet you storing your bitcoins on( whether it's on a custodial or non custodial wallet). Security in the crypto world is a whole different ball game if you think about it.. imagine downloading a third party keyboard on your device only to find out later that your wallet i drained because that was a your source of compromise..like I said security in the crypto world is crazzy.
Bitcoin is fast and reliable 24 hour's without breakdown except one's network is unstable due to one's location.
In conclusion
The fact that I have lived to see the Bitcoin network kind of break down when network was spammed with dust transactions to the point of pushing fees to over $100 per tx.. honestly I would say it's 90% reliable and only because we have other safeguards in place today like RBF, Segwit BTC etcetera which makes it reliable
