Are there any Bitcoin ATMs anywhere in the world yet that allow you to buy any Altcoins?
no through out world has no like that ATMS. from atms we have to withdraw money like that atms. but up to now like that atms not came if you want to change your coins in to alt coins in online we have more sites in online so onceyou have to check in that and invest. for that no need any atm centers. if you want to change in to alts then try directly in online. but you have to buy best coins for your use like bit coin has great demand present so you have to buy this coin and next lite coin, ether coin and other alt coins.
