"Remember, buy low, sell high" well said. This is simple tactic to get success in cryptocurrency .I did not panic in recent dip instead i bought some coins. This type of dips give us chance to get good profit at little period of time. Steem and bts are in great dip so we get good chance to buy. Rumors of a Binance hack caused a flash crash in crypto market but it is temporary nothing is fundamentally changed.
This is a better tactic than waiting until prices are high and then buying when everyone else is or panic selling the bottom.

• Buy incrementally as the price goes down, creating an average position and aiming to buy more as the price decreases further.
• Wait until the price settles, and perhaps even shows signs of recovering, and buy at that point.
• Set buy orders at lower prices than the current price and let them fill. Setting buys just before historic support levels, large “buy walls,” and psychological levels is an especially good strategy (as prices tend to do at least a quick bounce off these levels).
