I can clearly see that there are other cryptocurrencies that are beginning to dethrone bitcoin, showing off there quick and secured transactions, though bitcoin continues to be the king. What does bitcoin need to improve state your opinions.
In my own opinion, I think that there is no need for the bitcoin to improve its sytem. It was developed less than a decade back the and it seems like the people loves the way it is and the way how bitcoin work its system. If ever that there is an update with it then I think it is the time that bitcoin should pursue lightning networks to it because it will help for more good transaction to become faster, easier and it will help to lessen the charges of the users.
