The $DODO and $TRU I bought will have great benefits behind them; hold patiently for a few months, don't care about short-term fluctuations of a few points. The $TROY profit has been switched to PDA, and when everyone is cursing, it may be the time to buy at the bottom. Of course, risk and opportunity coexist, invest lightly and take a chance, don't be greedy, and avoid leverage.
