such mistakes happen because of inexperience. most people lose their money that way. I hope this has taught you a good lesson and you will not be so wrong in the future. I would advise you not to worry, just wait until 2018 is over, because it promises to be very positive for cryptocurrency.
Yes it is just a disadvantage for those who panic or do not believe in the future. If they believe in the future and see the great potential of cryptocurrency, I'm sure they will hold it for the long term. That mistake will be a valuable lesson for us.
