Can you buy Peepcoin at Coinexchange.io?
According to the DAPS website it says that we do not buy because the exchanger has put in maintenance the wallet ... something you know?
As far as I can see the maint is over. So you should be able to buy there, but be aware that they are not participating in the PCN->DAPS swap, so you will need to move your PCN to a wallet (or another exchange), prior to the swap date, if you want DAPS.
Do a small test buy and withdraw to be sure.
have if I understand.
1.- I bought PCN in bluetrade. If I want to have DAPS by PCN, should I send my PCN from Bluetrade to my PCN wallet?
2.- Where can I find the steps to configure my wallet?
3.- Until when can DAPS be changed by PCN?
Excuse the tremendous ignorance

It's best to transfer PCN to your own wallet, so you can be absolutely sure you'll get a 1:1 swap. Do you have a wallet set up yet? If not, there is a download link in the OP of this thread:

I can't really give you any information on the PCN->DAPS funding as I am not involved with DAPS. PCN will continue (as a separate network) after the swap. That also means if you have funds in your own wallet you will end up with
both PCN and DAPS.
