the obligatory 0.0001 transaction fee is a bit of a pita for playing around with these colored coins,
which are only 0.000006 each
It's not compulsory by Coinprism. You can send with none, but I don't know how fast it will be sent if at all. We can try sending it with 0.00001 BTC (1/10th of the suggested fee).
anyway I can't do anything with my 1000 owl unless I deposit more money at coinprism.
oh well. I wouldn't call it a majour problem, it just prevents me from fooling around with the coins.
