I've heard ppl should use a new address every time they receive coin to help anonymity. Should you use a new address every time you send? Can you just use the same address for everything? Thanks!
there are 2 reasons people say change your bitcoin address.
1. it helps make it harder to tell who you are... since your bitcoin adresse you give out keeps changing.
2. it helps you keep track of were you bitcoins are coming from.
* i have one bitcoin addresse i gave to my freind tom... when tom pays me.. i know it is him paying me.. becuase the bitcoin adresse i gave to him is were my money is coming from.
* i gave another bitcoin adresse to sally... when sally pays me... the bitcoins will she sent me will show up linked to that adresse.
this lets me tell how much tom and sally gave me each..... otherwise i would have to ask them what time they sent the money... and try to figure out who gave me what and when.

you can have as many adresses as you want.... any money you recieve will all go to the same place... you will simply be able to figure out who gave you what and when better if you have and label more then 1 adresse.
you CAN use the same adress for everything... but it makes it more easy to tell who you are.. and if you have alot of people sending you bitcoins it might get confusing as to who sent you what and when.
