I already stopped a couple of months but my friend keeps me encourage to stay here and be positive thoughts I could say that patience is the key of success... We must need to be careful and be courageous though it's hard to believe but we need it to encourage ourselves..
Yeah that one person must be your good and real friend who has given you good advice not to lose hope and keep on investing so same as your friend would say you, not to think negative, just have patience if you see the market is falling down because it will be good chance for you to earn money and have great profit though, I also use to tell people about good nature of bitcoin, I encourage them to keep on investing and not to stop having bitcoin in life as it is future maker.
