I have converted some BTC in BTS on the BTC38 web page.
It's defenitively better than ShapeShift. I got a much better price !
After doing a couple of buying BTS operations and sending it to my BTS account (small steps, I don't want to make a mistake a loose cryptos) I had some of my bitcoins "locked".
Normaly, They arrive in the "confirming" tab. When they are confirmed, they move to "available" tab. Once there, you can buy BTS. If you exceed the sellers, the rest of unselled bitcoin is "locked" because you have a buying position open.
I canceled all my open positions and my bitcoins doesn't move back to the "available" tab.
What I am doing wrong
