My question is what have been the developments in bitcoin are the.devs working on ways it can actually be better than using real money and never turning back.
Plenty. Privacy and efficiency enhancement of multisig for example.
Reason I asked about 0 confirms for small things is because I've never had a low fee confirm be rejected I've had it take 4 days to get confirmation though lmao.
It wouldn't help if the main problem is with the timeframe that it gets a confirmation. Merchants used to accept 0 conf transactions because the risks of it being double spent was relatively low in the past.
Like its there why aren't exchanges adopting it, that way consumer wallets will also and then many retailers will start accepting it again but this time it will accepted a lot more than the old days. Since the only thing stopping retailers is the cost of transacting with btc for everyday purchases is not worth it when you have cheaper options using a Visa card
Lightning network is ideal for smaller payments and it still relies on the user to open their own channel in order to transact. It'll also mean that there is a limited inbound capacity if the user is new and thus wouldn't make it viable for people that deals with larger transaction infrequently. Some smaller merchants has already adopted lightning network and it has provided more benefits for smaller transactions than those bigger ones.
** Lightning can alleviate the problem but it won't solve onchain scaling if and when Bitcoin gets an even greater adoption.
