I think investing is not for everyone it does require luck.Because I first bought some dollar amount of bitcoins.First I was in loss then recovered and made some profit but still not selling then not selling now again in loss.
Everything can be arranged with the passion that you have, if you feel that everything is very heavy and there will be a loss that will come, you should sell it. but you can be patient until the price returns to good for sale and continue to be enthusiastic, don't give up.
