The time a bitcoin user lose is when he/she sells at the lows. You can't consider it a profit or loss if you still have the coin holdings unless you sell it. It's important that you always set stop loss and sell targets on your trades to avoid such unfortunate smash on your portfolio.

I'm really sorry, but that is not working that way!
somebody have to loose, cause someone will win
this trading stuff working like this, if there is no loss for someone, then that mean no profit and hence no trading!
but because we see trading, that mean profits is there. and losses there are as well.

it seems that if you are a trader at the beginning of the game there is nothing that never loses, all must have experienced a very deep loss so if it never loses it is sure they lie to you and yes it is also possible that all users experience a loss when bitcoin is no longer priced .

Yes because greed is curse and it is the only way people lose money because they become impatient and they sell when the price become 20% high only, they use to think it is the time to sell, and they refuse the high profit for the sake of small profit only, as much as time passing bitcoin is getting expensive we should take step towards it, at beginning of bitcoin make yourself determined not to be in rush and not to be greedy because these are the only things which cause huge lose in crypto currency investment.

That is never possible. People lose everyday depending on the decisions they make with their bitcoins. Panic sellers will always lose and those that always want to be greedy about the profit they want to make will always lose.

You get the money the other one has invested.But you only win if you sale at higher price then that you invested.btw,there are more people losing money than those who wins at trading.

That is never possible. Losing bitcoin is a normal everyday thing. Someone has to lose for someone to gain. Panic sellers has to sell cheaply for buyers to make profit from it. Its the normal trend.

I think it's impossible because if that happens the price of Bitcoin will bubble.

it seems not like that I think there is some that is not for if the profit may all bitcoin companies will lose this in my opinion should be the balance between utung and loss so bitcoin company can play money.
