I've recently signed up to ***, to view the activity of investors and sentiment around 3DP. One forum post by the owner of *** (I'm assuming at least, correct me if I'm wrong) doesn't feel overly confident in 3DP's uphill climb (see full post here). If his publicly presented portfolio is anything to go off, he has been doing some massive selling of shares recently. My thoughts on this are not strong, I'm confident where 3DP is going even if is just based on 'momentum and technicals', but at the end of the day I knew nothing about disallowed 3 months ago (lol). What are other peoples thoughts on this post?
