Wow, I try to imagine how you felt after hanging up the phone, for sure it's hard to explain a phenomenon like Bitcoin to someone who maybe know all about just from news, and I am speaking generally here. I remember last December I had a similar discussion with my friends about BTC, back then the price went from $700 up to $100 and the panic was created, some of us said the best investment is to sell urgent, some of us chose to believe in it and give it more time to see how far can it go. It is hard and complicated sometimes, when so many news, facts and predictions are meant to underline a lifestyle on the crypto market, but after all it is the personal choice that matter the most. If you trust BTC and decide to have patience, I am more than sure you will see even higher point for it, after all, as you already said, it has fallen 20 percent in a day but rose 100 percent in a month, so it doesn't mean big loose for someone who invested in BTC in the beginning of the last year. Day by day more people catch the fever of crypto currencies, and that helps a lot. More invested money, more stability. So trust your gut. Wish you a fresh mindset, and Merry Christmas!
