Yes! Assuming you plan on leaving it there for awhile. If you add more you won't have to restake since your wallet will already be registered.
And , Sorry for the late reply. Hadn't quite figured out Steemit yet.

Hey, I transfered the Stellar to the Interstellar-wallet on my mobile phone (not a pool). Just staking KCS, KMD, Stratis and Neo at the moment.
No problem, so you found the "replies"-folder now ;)

Haha, right.
If it is in a wallet, you may as well stake it. You won't regret it because it is a one-time thing. Off-exchange wallets are definitely the way to go. Wish your staking goes well. I definitely prefer it to mining.

I would love to start mining as well, but it´s impossible in Germany (cause the high power costs).
