1. Learn to read charts, this is vital. I made the mistake countless time of buying at the top of a rally and ended up as a bagholder. There was a sell signal somewhere at 740 USD.
2. The markets do not care about you or your perception. If it proves you wrong, you have to be flexible and sell. BTC and Altcoins are controlled mostly by whales.
3. Most BTC volume originates from China, they don't care about Brexit.
