This event contract really cooled me down! I was once making a profit of 2000u, and in the blink of an eye, it turned into a loss of 500u. This rollercoaster experience is too thrilling, and I've decided never to touch it again! In comparison, contracts and spot trading are much more reliable. I firmly believe that Bitcoin can reach a new high, perhaps even this week! From now on, I will invest in Bitcoin steadily, not seeking to get rich overnight, but wishing to make steady progress towards financial freedom, slowly accumulating wealth and starting my own path to wealth growth.
