hello. can any one tell me how to deal with the wallet ?

i download it when buying at ico and receive the coins on it without problem , but how to be safe if it deleted ? what can i do ?
also i receive the staking coins without doing anything even if i closed the wallet and open it later i get the staking also . thanks in advance
FIRST IF YOU HAVE A PASSWORD SAVE IT WELL, WRITE IT SO YOU WILL NOT FORGET
THE "SECOND" FIRST

BACK UP YOUR WALLET.....open the wallet , click (on top of the wallet) file, backup the wallet, choose a directory to save....it will create a wallet.dat file(or whatever name you put on it)....safe that file ...DONT LOSE IT OR YOUR COINS ARE GONE...EVEN CREDENCE TEAM CANT RECOVER IT.
Also , to be safe, i personaly save the file where the wallet is installed.....it is located in this directory
C:\Users\(the name of your pc)\AppData\Roaming look for credence
I do a copy of it too..and i save it ....do 2 backups , just to be sure....this coin will have a price of at least 20$...So you better not lose it

And remember to hold the coins good and dont sell at stupid low prices

i get the " wallet.dat & \AppData\Roaming " thing and i will do it .. thanks
