Next to each advertisement on the website the price of a Marycoin for that advertisement is shown as currency per Marycoin. For example, if we are buying Marycoin with the currency US dollars the price would be shown as 420 USD / MC. This means that if I wanted to buy 1 Marycoin it would cost me 420 US dollars.
Can I buy less than 1 Marycoin?
Absolutely! In each advertisement you see
what's called limits. That shows you the least and the most amount of Marycoins that you can buy
from that advertisement.
One Marycoin can be divided into much much smaller pieces, the smallest piece is called one satoshi and is the same as 0.00000001 MC.
