Swapped my little amount of BTCDs successfully and I see the KMDs in my ICO site.
What is the next step to get my KMDs to a wallet?
I installed Iguana wallet and created a KMD address.
Is it recommendable (because it is Beta) to let the KMD payout to this wallet?
Or should I wait until stable version is released?
You must a request a payout from your Ico dashboard. Please be careful to backup your seed! Payouts are processed once every few days. If the wallet is beta doesn't matter, your coins are always safe in the blockchain. Next wallet version should be much improved.
