I think it can be possible by doing some tweaks and updates on blockchain itself or updating some old stuff handling bitcoin transactions pretty sure thay may help in making bitcoin transaction a bit faster or even be instant just like Xrp.If xrp team achieved it why not bitcoin can right
This is the classic blockchain Trilemma. It's not possible (or not yet) to be fully decentralized, highly scalable, and have a strong security. BTC is clearly fully decentralized and is a high security network, but the scalability isn't that high. XRP is more centralized and in favor more scalable. In my opinion is BTC at the moment, mainly a store of value with the opportunity to make fast transactions on the lightning network.
BTC has the best properties to be a store of value and if you see BTC as a store of value the transaction time is very quick compared to classic store of values like gold, silver and so on. Fascinating is that BTC has many use cases and with the time we will see how BTC will be used.
