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.
I think there is nothing to fix with bitcoin, because bitcoin is very good, but only one is possible for us with the problem of delivery that sometimes, long to wait until 6 confirmation ...
I hope you are joking because there is a bunch we can fix currently. First off we can fix the speed and fee at which we transact because they are not up to par and with LN coming that will change hopefully. Privacy is also another issue but upgrades are incoming to take care of that as well. Other than that I don't see much need for improvement, it is not like we need to make Bitcoin great again
