Hello,

if you are new to bitcoin and think of trying it do not use purse.io. I had to use it to convert money from Amazons Mturk to bitcoins. And they are the only option for this.
The staff of purse will block your account if you ask critical questions. On their system errors or about their bad treatment of sellers/ buyers.
I do no talk about you cursing or insulting but on normal critical questions. They will disable your account.
And they will confiscate your bitcoins.
They have many problems in their system. Buyers that don´t pay you is at least 50% of the time. This is then arbitrated after many messages and days of waiting. And they don't punish these buyers so they continue trying to steal your bitcoins.
Also for your info, purse has no address or office or contact or phone number where you can reach them. Only an anonymous chat in the website where they stay anonymous and do not respond if you have comments or questions they dont like.
My account was disabled. Without any reason. Without any notice or emai.Not before not after. And my bitcoins are confiscated.
 there is a thread on Reddit about it now.
You can use it but it is a high risk.
