In participating in testnets and expecting rewards know that you can get scammed by them if they ask you to send real coins to their site or another site. Avoid any testnet asking for that. Another bad thing about testnet is you do not know what task they can add up in the middle of the process and then you will be left with no choice than continue with them when you do not like the new tasks. If you have money to invest, the best thing is to avoid testnets. Wait for the token to list and buy.
