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.
