Taking into consideration the nature and redundancy of Bitcoin technology and the difficulty in scaling, I am very curious to know if Bitcoin protocol will be dropped one day and another coin build to take its place. because now it's almost like the redundancy of Bitcoin and the time it takes for a transaction to be processed is part of what is affecting its mainstream adoption as a currency. please share your thoughts.
I don't think so. Look at how Etherium performs compared to Bitcoin. Taking over the king and father of cryptocurrency is too far from happening. Bitcoin has a strong community, it has the support of some countries around the world. It is widely used as a payment method and the system itself is reliable. No altcoin will ever be greater than Bitcoin as they will all remain alternative coins.
