Odaily Planet Daily News: Former Mt.Gox CEO Mark Karpeles said in an interview at the Korean Blockchain Week that the current industry has too much centralization risk and too many scam projects. "There are too many such projects, and I use the word bad in a very broad sense, because it is either a scam project or a project that does not bring any new content that is too outstanding." In addition, Karpeles did not forget to promote the hierarchical deterministic wallet (HD) technology, and said that if there was HD technology in the Mt.Gox era, the tragedy would not have happened. It is reported that HD is a wallet that can securely manage and generate multiple public and private key pairs, which is generated by a master seed.
