Secure Coin, English name SecureCoin, referred to as SRC, was born on August 9, 2013. The reason why the currency is called a safe currency is that it uses a combination of 6 hash algorithms for data encryption, and it is known as the safest virtual currency. SRC generates 1 block every 1 minute, each block contains 5 SRC, and the output is halved approximately every 4 years. After the release of SRC, it was once strongly sought after by the market.
