If 3i don't stop BTC investment of Angelshares. The PTS price will be going down gradually. I don't think allowing BTC investment is a good idea for PTS holders. 3I shoud stop BTC investment right now and only allow PTS investemnt to protect PTS value. Think the aim and value of PTS is that it can obtain BTS, now you can get more BTS using BTC, why should you need PTS?
