I think he was refering to buy sex with bitcoins 

I am focusing on GNU/Linux, but this can also be used on other Operating Systems where gpg/gnupg is available and it doesn't require you to generate a keypair because we will use symmetrycal encryption (quite secure still).

If you are on the command line, for encrypting you just have to run this and introduce the password of your choice:

This will create a new file called wallet.dat.gpg, so you still need to erase the original one (if you secure delete it with some tool as shred or wipe, much better for your security).

And the way back, for decrypting you just do:

Introduce your password and you're done: you have again the original wallet.dat file and you can delete the encrypted one.

If you want a gpg/gnupg GUI for managing this, you can get a simple one like GPG GUI (easy compilation, just make && make install): http://www.garyshood.com/gpg_gui/. I won't explain it's usage because it's self explanatory

Hope it helps someone! Cheers!

Bitmarket.eu has also it's protection mechanisms even with no funds (I think it does this by locking the bitcoins to buy/sell in the accepted transaction into an intermediate wallet until the payment process has been done between particulars, but that's another story).

As I said, I'm not planning to pay any fees and I don't want a site that requests funds to operate with (like MtGox or Tradehill). Bitmarket.eu doesn't need such requirements and that's how I like it to be.

Oh, then maybe there are only problems on dispute, but it's still risky business, so I try to avoid Paypal as payment method

Thanks Maged, I am not sure if I'll be patient enough, but at least I'll have a look at the channel.


Wow, didn't know Paypal was that evil with bitcoin. Won't use it as a payment method, so I will have to strictly use bank transfer or credit card. Thanks Tronlet.

Haven't requested prizes or forecasts, so please, stick to the subject when answering. Thanks.

Hi there Frank, I appreciate it but I rather using some exchange platform for the benefit of all.

Thanks ploum, seems a good site to operate with.

Thanks Freemoney. I guess there are other ways of trading without fees but less reliable (in instance, trading with individuals via other ways such as paypal, etc).

I am new on the BTC world and only know about websites (MtGox, Tradehill...) that offer trading by paying some (small? really dunno) fees. The question would be: Is there any other good (secure, reliable) way to trade online WITHOUT FEES? If that had been asked before and the answer is already on the forums, I would be gratefull if someone points me to it.

Thanks & cheers!

Edited!
