share experiences, Buying and Selling Bitcoin when prices are high is risky. surely a bitcoin trader has experienced the name of loss on bitcoin so how big is your nominal loss in bitcoin trading in your life? and is there any suggestion to reduce or avoid loss on bitcoin 
?
I am not a regular trader,but I just tried trading with altcoins in long term.I didn't face any big losses yet but the biggest mistake made by me was bought the litecoin at the peak price and then late sold it for very cheap price.?me too, I also have not faced any big losses till now but I have made many mistakes, I could be easily millionaire if I hold.
Because you are not regular traders you people don't understand how wrong headline is. Failure of trading is wrong, there is failure in trading, it's individual trading and individual mistakes, trading as it is can not be failure.
Simply trading if it's done good should be profitable if it's not good then it's failure.
Holding is good, It should be beginning for everyone. You can't trade relaxed if you don't have back up, that backup is the amount you hold on a side. Who bought 5 years ago or later and holded is a millionaire, the ones who arw buying now should be prepared to wait 5+ years.
