i had some stock in HIVE Blockchain Technologies, their business model is that they provide secure servers for the blockchain transactions to be complted on, and in turn they can charge a small fee in bitcoin. the SP skyrocketed by 6000% over the course of a couple of months. cue my poorly timed entrance to the stock, i was up $2k in a couple of days ($1200 initial investment) so i bought some more and it went up for about 4 hours and then tanked. tried to wait it out but finally pulled the plug for a loss of $800, and its still not back to where my required level was.
i am still investing in weedstocks right now, started on Sept 20 initial investment of $10k, as of close today i'm up $7200 which includes my loss mentioned above.
