Developers' ability is limited,
From the beginning of ESP1 to ESP2, has been claimed to be integrated mining function, has been unable to achieve,
In the wallet into the function icon mining which is easy to implement,
In order to achieve automatic upgrade wallet function for a long time did not succeed, however, automatic upgrade wallet function is not important,
The ESP2 wallet appears to be very hasty, take BlackCoin's wallet to do the two development is not even modify the name to do,
POS ESP2 function is not complete, a lot of POS to the reward can not be successful, it is too sad.
This may be the market can not accept the reasons for ESP, there is no strong developer.
Developers spend too much time on some of the functions that are not important, but the main features are nothing. This is a disappointment.
