===> What exactly are Monaco tokens used for?

Monaco tokens will  give you the right to claim a pro-rata portion of ERC20 in our Asset Contract. Monaco will send 1% of all transactions funded with crypto to the Asset Contract.
In essence this creates a very strong link between growth in our platform transaction volume and growth in Monaco token price in secondary market.

===> and will we be able to trade them on mainstream crypto exchanges?

We will be announcing the exchanges before the Token Sale is finished.

====> I see you use the VISA brand a lot in your description. Is VISA onboard and why would VISA choose this token where many others have failed to partner with VISA?

We've singed an agreement with an issuer (Principal Member of VISA), we're now in the process of becoming a program manager.
There is quite a few crypto cards in the market, who have successfully partnered with VISA. Monaco is different in 3 crucial ways:
- we give you perfect interbank rates on fiat currencies, effectively saving you a ton of money
- we have probably the sexiest card in the market
- our platform allows BTC, ETH and soon other ERC20 tokens as funding sources, without compromising stability, security and, last but not least, without asking you to convert to fiat on deposit
