Damn, definitely overlooked one of the more important points.
I know that they are currently only hosting competitions and that tokens will be available soon. But could clarify by what a MetaToken is ?
Thanks in advance !!

The prefix  meta implies that it is behind o even inside token.
It is my understainding that meta tokens are made by burning (or destruying) another coin, which backups the value or the newly created token, and this is called proof-of-burn. I assume whaleshares are made by burning steems (or perhaps bitshares[?]), haven't asked. 

Nope. Dont need to burn steem when u can power it up to make the whale you summon stronger... ;)

i wonder if we are talking about the same thing.. I am talking about how meta tokens are made. A quick search:

*"In order to create the initial meta-tokens (XCP) that would travel on the Counterparty protocol atop the bitcoin blockchain, the protocol’s developers did something interesting: they enabled any existing bitcoin user to obtain XCP by provably “burning” or destroying some amount of bitcoin, this is referred to as a proof-of-burn. The purpose of this setup was to create a fair initial distribution of XCP tokens, and avoid a situation where Counterparty developers (by selling XCP) would be enriched—perhaps unfairly—before the platform bore any real fruit."*
