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.
The first thing that I want Bitcoin to improve is the speed of the transaction. It is very slow, usually I have to wait 1-2 days to make his transaction. Then the transaction fee. It's tall and unfriendly to newbies and little money.
