Hey there Gracechen17!
Just a bit of correction on the charges you mentioned. A very minimal charge of 0.1% applies when using Bidium tokens on the exchange platform compared to 1% when using other tokens.
As of the moment, Bidium announced that it will be accepting Bitcoin, Litecoin and Ethereum apart from the main token, Bidium. But fear not for other alt coins as many will be added later on.
The project is at its early stage of its production and its very experimental I wish that this project have a community manager or community pages on facebook, twitter and other social media sites. This can hugely help the boost of popularity and token sale of Bidium in their ICO crowdsale.
Great idea, I too believe that this can really be a big help for this project to be able to reach out to various types of people and to increase traffic more that may come to this project. But I think we should worry not about this anymore since the team might have probably thought of this already.
