In an official statement from Cardano, ADA holders are warned to download Daedalus Wallet ONLY from the official website https://www.cardanohub.org/en/home/
DO NOT TRUST "Street Gold"
The company "Street Gold" is producing an unauthorized product targeted at stealing your balance by obtaining your Cardano credentials or getting you to transfer your ADA into their possession.
After doing some additional research, it appears "Street Gold" is also offering other "Crypto Wallet" products. THESE WALLETS ARE NOT SAFE!
Just because something is listed in the Google Play Store does not mean it is "safe". Do your research before trusting ANY product that interacts with your cryptocurrency!
