What I can say about this is stop panicking whenever the price of bitcoins decreases so much in the time before bull runs because that's the traditional way before the bull runs start and you won't get any chance to buy again because, after that, the price will continue to rise until it reaches a new ATH. Whatever happens, just focus on your goal to achieve and ripe as much income as this upcoming bull run just be patient and persevere on everything.
You will be able to control your emotion better if you invest with your money, only with your money.
If you borrow money and have pressure from interest payment, collateral liquidation, margin call which are all big risks, you will lose control on your emotion. I am sure many people will feel panic when facing with such risks. Lastly, feel fearful, panic or not, the market will move in its way and your loan collateral can be liquidated by exchanges.
Even you don't want to sell, your coins will be sold by exchange and you can not do anything. The best way to avoid liquidation is using your own money to invest, don't use leverages because you believe you will win and will get rich with your accurate thinking and greedy position.
