Minimum trade is still 0.1 BTC.... why so high... Put it back to 0.01.
This happened about a week ago also, but it fixed shortly afterwards.
Seems to be happening again now.
Oddly, it appears that
https://api.bitfinex.com/v1/symbols_details reports the minimum order size as 0.001 btc
Yes - I had a response from Raphael a few days ago: "The minimum order is still 0.001 BTC, however we have implemented an antispam rule so that you can not place an order of less than 1/1000th of your avalable balance in a currency/wallet unless it is more than 0.1 unit. The reason was an increasing amount of orderbook spam with thousands of tiny orders".
They did set it back to 0.01 for a while, but now for whatever reason they've rolled the change back again.
