Yes it dropped below $2 but the strength it is shown is still valid. The BTC price hasn't dropped below the last support and there for sure was resistance at $2. Then, as you say, there was an AirDrop which finally broke the resistance as someone sold off some $ONIONs.
It is impossible to predict the market and if BTC continues down I don't expect DeepOnion to go against the current. BUT if the market turns around to bullish, then we could have 5-10x easily with this coin in a short period since then people won't sell cheap is my opinion.
