Make sure that you are holding your bitcoin until 2020 at least: there are so many impatient people. IF you want to be involved with bitcoin it is best that you try not to be impulsive. You have to make sure that you are buying and holding until 2020. When bitcoin drops I'm fine because I am just thinking about 2020, I know what's going to happen. In 2016 there was a halving, and the price of bitcoin doubled. What is happening is that people are too tempted and have done well in terms of paper value. Also make sure to never keep your cryptocurrency in an exchange keep it in a wallet.
