this means and who pays which. I made two sell xcp for btc orders. The first one was matched and expired without btc pay. I then cancelled it. The second time I just let it expire. Now my btc balance has been reduced permanently. Really? So just putting up innocent sell orders and nobody buying them results in me losing btc? Please explain for all the non techs.
In order to disincentivise trolling of the orderbook, offers to sell BTC must provide a fee to miners, which must match the 'fee required' by orders buying BTC. The default fee is 1%. You can extend the expiration time of your order when selling BTC, so that the fee paid per unit time is as low as you want. I've just opened up a GitHub issue about this, so that the default expiration time for BTC sell orders is greater than for other orders.
Yes but I was Buying BTC. Why was my btc balance reduced permanently twice after 2 unsuccessful orders.
