Hello,
where is the best place to stock ark ? I don't want check every month it's for long term.
Thanks in advance.
If you're going for the "best" that would be a hardware wallet.
I'm using Ledger Nano S for that purpose.
If you want the 2nd "best" method when it comes to the safety of your private key, then a paper wallet will be enough as long as you don't lose the paper.
You can find the official paper wallet generator here:

You have to vote for a delegate and yes, it's safe because nothing leaves your wallet.
You wallet address has a voting power equal to your ARK coins, you just choose a delegate to support with your wallet and you'll receive a portion of the coins they forge (aka "mine").
If you load your wallet with more coins, your voting power will increase and you'll receive a bigger portion of the delegate.
Some delegates might share big amounts of their coins while other might share less but might spend some of their holdings to support ARK in different ways, like doing marketing work or developing apps.
Just google "ARK Delegates" and you'll find a lot of info about them; make your own choice!
