That's not an "advertisement" that's a masternode listing. MEDICcoin does not control the BTC price that those platforms use. Obviously everyone should do their own investigation into correct BTC price when calculating returns.
I can tell you that the BTC amount shown is currently wrong because in about a week with 2 mn I get .1673 BTC which is around $1159.89
I've already recouped my investment much over and I have not sold my "deposit" MEDIC yet.
This coin is here to stay and it is a "real" coin making "real" progress. Of all the MN coins I have invested in (yes some were scams) but MEDIC is the one coin I have faith in the developers and the idea. They actually meet and exceed the Roadmap and real people behind it.
Actually they do have control over it. The founder of Medic Coin owns Cryptomat.com
