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

?
It is critical to answer for me, In current trend every new investors are loose some money and they will earn more profit so all are forgot the losses. But My suggestion also same thing because you should plan to your own method you will loose some money but quickly understand the trading possibilities. At the same time you will expect some other help you are not a right trader so I do not suggest anything in trading investment.
