Minexcoin is pretty strong during this dip! MNX (-13.96%) / BTC (-14.08) So not so bad but still very volatile if you ask me. Algorithm should be working harder!

Volatility is relative. They states that MNX is low volatile relative $ price of 10 main coins. For the simplicity sake, if BTC falls 14.08 (relative to dollar) & MNX falls 13.96 (relative to dollar) then relative to BTC price in dollar MNX grows 0.12%. Very stable, non-volatile.
Yeah but as far as i know its bound to US$ and there is a loss about 10% atm and thats not growing. Cause the difference of 0.12% is a profit against BTC not US$.

Not correct. It is bound
not to dollar but to
price in dollar of 10 main coins. Read whitepaper once more.
Now iam confused

The Price of the Coin decreased from about 33 to 24.
Whats the difference ?

It is simple. If you understand maths of course. Please read pages 5-7 here

But in few words, if top 10 coins going up or stays at same level MNX growing up but if total price( example 7 of 10) of all top 10 coins going down MNX going down as well. It is very smart system, so simply relax and enjoy percents in bank
