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.
I agree with the things that are mentioned. investments has risk and investors should be awared of that particularly on instances of losing profit. Especially on cryptoinvestment whereas the risk is due to the market volatility. So an investor should be wise on choosing where to invest your money with.
