Download? Lottery app? That sounds like a bad combo op which is why I won't be downloading it and I recommend others to do the same unless the app proves its legitimacy over time.
Being paranoid is the only thing which have saved many people holding Bitcoin from losing it all to scammers, hackers and fraudsters.
Well said. It's odd that you were the only person so far in this thread to talk about the risks of downloading this app. Smh!
