Hey everyone first post.

So I just bought into maidsafecoin and did it from an address that does not give you access to your private key (coinspot.com.au) .  If I ever wanted to send or move them do I need access to it or is there another way?  Im still new to cryptos and the only time I have seen my private key was for a short time when I moved coins offline through multibit.


Had a look through similar posts but couldn't find an answer.

Any advice?
