Because you mentioned about apps, my recommendations are
- Don't search (when you are looking for apps) on Google Play or Apple Store. You will highly be trapped by faked apps, especially on Google Play.
- If you want to find apps from exchanges, go to coinmarketcap or coingecko, get links to official websites on which you will find links to download apps. Get links on official websites.
- Same advice when you need to find websites of crypto projects
- For wallets of new projects that are not listed on coinmarketcap or coingecko, you must be very careful because they might contain malwares. Report Malware and Suspicious Links here so Mods can take Action !. Read that topic to understand about such risk.
Thank you very much for your comprehensive information and advice. I really want to give you merits, but unfortunately there is no more. I will add the content you provided, thank you again.
