Try to choose a business with high success rate to make money, and look at the account flow in advance. First of all, I want to make it clear that speculation, like stock speculation and futures speculation, is a relatively heavy speculative nature, and speculation involves more uncontrollable factors. For example, exchange fraud, hacking and so on, it is impossible to completely avoid risks.
However, we can reduce the risk of investment by hedging. The concept and method of specific hedging can be searched by yourself, and here I will talk about the general core. The core of speculative currency hedging is to use leverage and as hedging.
For example, you can use the leverage services provided by some exchange platforms to make more coins. As long as the currency price does not fall below the balance line, it can be operated with leverage of 10 times. On the other hand, you should look for another coin that may have the opposite situation after your currency goes up and down, or make some empty coins directly in another exchange, so the risk will be reduced.
