Just to correct one thing mentioned here.

Paxum transfer by personal account is 0.25 and paxum transfer by business acount is $1.

So if you as personal account holder send money to any other personal/business account it would cost you 0.25 thus if you deposit your funds thats allready in paxum to an exchange the deposit fee would be 0.25 and when you withdraw from an exchange it would be $1, all these fees are fixed fees.
