It is a market where only spare money should invested which you are ready to loose ,no need to grumble now wait and watch as per your statement you are already looser.
This is true that only spare or limited money should be invested as everyone know that market will rise and also it will crash . So either one should have holding capacity or be ready to face the fall and losses if need be . One has to move on and cannot just keep on thinking about it .
That is why i am only working for bitcoin and earning is against my skill and bounty campaigns, so it is only my time and skill is invested and in future if it goes zero also it wont affect me, but i use it when ever i am in need of fiat currency.
