There are two basic things that need to be implemented when the market suddenly falls like yesterday to make a profit. First, the attitude must remain calm by thinking that it will recover. Second, take the opportunity to buy as many coins as possible, such as top 10 coins.
You are very right these two basic things will give us advantages like success and win in the market firstly in terms of calm i.e trust that BTC will recover and rally again be sure and follow your own decision. then the second thing is leverage and this also comes with recklessly betting on coins and buying at low prices I often remind myself "be greedy when others are fearful" those are the key factors key to help you succeed in this vibrant market.
