1.Only invest what you can afford to lose.
2.Never invest in something you dont understand.
You wont immediately understand everything, thats ok. Do some research.
3.Dont day trade unless you spend a minimum of 6 hours a day on the markets.
4. Be patient and buy it on sale.
For me, the first of your rules is a must. Peoples who invest more than they can afford to lose are a gambler.
Cryptocurrency is not a gambling platform, it should have calculation when you investing on a project. Always dyor when you want to invest a project.
