Loss 86% - lesson must be learned

I bought Sea(se) and Xiao Peng (9868.hk), both lost -86% so far and still in my portfolio. 

Lesson learnt? 

I bought them for the "dream" that they will grow as they were growing, although their foundation not so solid and still blooding too. So the buying is like a blind gambling. Both of them have no obvious moat in competitive industries, In other words, their business model is worrying. I should be gamble on them. 

I will keep one of them in my portfolio to keep reminding me what can be the consequence of bad decisions!
