The site operates under bank-level security and it offers a multi-coin wallet-service, with low transaction fees. Calling these fees low is obviously a subjective matter though: one of the main complaints regarding the services offered by CoinSpot is that its fees are way too high.
The site does not feature an About Us page, and learning anything about who is behind the operation is borderline impossible. From the About section of their Facebook page, we learned though that the actual address of the exchange is 114 William Street, Melbourne, Victoria, Australia.
