Don't mix Bitcoin with crypto aka shitcoins.
Bitcoin is still practically a crypto, that mix that up. Crypto is a broad name while, bitcoin is just a variety. The main difference come in the sense that, any other coin other than bitcoin is an altcoin and this is due to the fact that, bitcoin remains the pioneer, truly decentralized and priced currency amongst all other coins out there.
I made a transaction through my bank, Fortunately the money was'nt received by the suppose receiver and i was debited.
I went to the bank for transfer error issue, spending more than 5hours trying to get access into the bank(due to crowd) and 3hrs trying to fix the transfer error.
Unfortunately you mean buy yeah, these things happens and the smart thing to do is making complaints using your banks Mobile app. Cryptocurrency has made banks to be playing catch-up on means to ensure proper online banking, ease of making complaints and resolving issues. You don't need to go to the bank, there is a customer care personnel on there to engage you on chats and resolve your issues. Engage them some times and there won't be much need in going through those bank walls.
My point here is that, if i had sent the money in form of crypto(Bitcoin), my transaction would have run smoothly, the only way i would have had an issue was if i had transfer to the wrong address.
Bitcoin transactions don't always goes smoothly. There are issues of mempool congestion which you can over come by increasing the fees perhaps. In cases where low fees are been used, you could as well end up waiting for a day. This doesn't mean bitcoin isn't a better payment option than conventional banks, just telling you what could go wrong.
