It is so impossible to trade without any single loss. But the thing is we can compensate every loss thru average down. So do not trade the whole money 100%. Always trade in portion. One more thing do not trade using margin if you dont know how to manage it.
I certainly agree with you. All kinds of investing are risky and that includes bitcoin. What you need to do is just to be patient and wait until bitcoin's value reaches your desired amount. Also, you must have atleast a second option or a plan B so if ever trading or investment fails for, you'll still have a good option. Be patient and you'll get a good profit in due time.
