$list Shows how many coin you have
 $buy [amount] [what_you_want] [what_you_dont]
 I think of it like: xchg, I want to buy 100 bitcoins with US dollars.
 example: $but 100 BTC USD
 $sell [amount] [what_you_want] [what_you_dont]
 $give [amount] [type] [their_nick]
 I think of this one like: xchg, I want to give 100 bitcoins to my_bro
 example: $give 20 ETH epoch
 amounts can also be percentages or "all" which just gets turned into 100%
 these percentages are based on the amount of money of the type that is being spent.
