Avoid $BB as we don't have enough data to deep dive into the analysis. If you are willing to take risks, use leverage as low as 5x. Because you don't know where it's going to land. Plus point, if you look at its supply most of the supply is locked. Look at Total and Circulating Supply. So, I would suggest to avoid this coin or trade in short term (quick scalping) with proper strategy and risk management.

Note: Please do your own research and analysis before jumping into any trade.
