BTW, could you make an advise to me on what to do right now? I'm a little bit depressed.
You really need to control your emotion if deciding to invest in bitcoin. Bitcoin is a very volatile asset and it continues. Everyone probably already knows that changes in bitcoin price can cause losses for investor and trader if they panic. As we all know, the risk will always be there and will never go away. Nonetheless, I think bitcoin has always had the potential to benefit traders and investors alike despite its high price. Trust that your failures this time will be a good experience to start things off on the right.
