I bought some ARDOR since the price has dipped lately. I downloaded the wallet but was wondering is it best to keep ARDOR on an exchange or send ARDOR to my Wallet? Jut want opinions.

Also, I am confused about what an ALIAS is? Do I have to create one or can I just deposit Ardor Tokens into the wallet.

One last question, can I send NXT into the ARDOR wallet? I have an NXT wallet but it would be better it seems to just store NXT, ARDOR and IGNIS in the same wallet?
