E. Snowden gave an interview to the researcher of CoinCenter P. van Valkeburg, in which he named the main drawback of Bitcoin's Blockade. He believes that the main disadvantage of this block is its publicity. He noted that developers need to pay attention to work on changing the situation, as using a public registry will result in outflow of users.
Snowden drew attention to the fact that in 2013 he was thinking of using Bitcoin to purchase server infrastructure. But he never used it. He stressed that the publicity of the register and the basis of trade can not be compatible.
During the interview, Snowden singled out ZCash technology. He said that she has good prospects for development. At the same time, he indicated that he continues to cooperate with Monero.
In the end, Snowden advised the holder of the crypto-currency not to advertise that they have assets.
Unfortunately, he is right, at the moment all types of modern Blockboys are based on decentralization and maximum openness. Snowden recalled that the NSA continues to actively monitor Bitcoin's Blockade. The Agency seeks to identify the maximum possible number of holders of crypto currency.
