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 bitcoin needs to improve its volatility to make it more profitable. And second, it needs to improve its transaction fees because it is very expensive to do transfers. And lastly, bitcoin needs to improve the speed in transactions transfer because it takes a long time to send and receive payment. So far those are the things very important to be improved in bitcoin.
