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.
Hmmm dethrone? No one has ever meet the standards to dethrone bitcoin yet. As you can see on the coinmarketcap.com bitcoin is still the number one and no one has ever meet the standards to dethrone it. Compare it to the other alt coins
Uhmm i think there is no need to improve in bitcoin but instead increase its investors, miners and spreading word about bitcoin is what it needs
