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.
Actually, Bitcoin is good, but Bitcoin has a lot of things to improve, starting with transaction handling, currency is limited to about 3-4 transactions per second, and more than that will only cause the entire system to be flooded with users, but the problem applies to all type of cryptocurrency, you do not see it in other currencies because only Bitcoins are successful in getting a lot of transactions traffic.
For me, bitcoin needs to improve the transaction and the security of the account of one user from hackers.
I've known a lot of people who lost thier money in bitcoin just because of hackers, also some of them hack accounts that have high rank. People who do not have a lot of knowledge in this business will lost their saving in bitcoin.
The number people who are not satisfied and contented on what they have are getting higher than before. The new generation now are really liberated that they dont care even they hurt other people, they only know is they are happy about it.
