Good thing I am using two platforms to trade, Binance and Kucoin. When that dip happened my internet connection are fine but the binance lags very much. You can't even add or close your open trades. And if you manage to make a buy order, it doesn't show immediately. Good thing I have an account on Kucoin and have some USDT there, I was able to buy some cheap altcoins when that dump happened. Their app didn't lag at all during those times. I guess binance should improve their app so that problem won't happen again or else they will lose some of their users.
Always good to have an alternative in case things like this happened, you'll be able to continue your trade even there's some issue with the exchange that you are using.
If you have options you can simply avoid using the one that have certain issue and proceed using the other one. Not new to this market even Binance also have some hardship either huge bulks of volumes or some issues with thier system.
Along the way, just wait for this to resolve then comeback using the platform again.
