I have been in forex and stock market for more than 10 years and I have learned a lot of things and I am trying to unlearn many things in other to focus on the one that works. Many people do keep a trading journal but I have never done that. I only write done my trading plan and strategies. In 2017, I came into cryptocurrency trading and tried to abandon the forex and stock trading and though there look similar I see some differences in stability and volatility. Cryptocurrency is volatile and in a few minutes, you can lose all your capital or miss a great opportunity.  the greatest thing I have learned is: when people are commenting "bitcoin is going to $20,00, bitcoin is hitting $50,000 before the end of the month! Be careful and sell because the market is about to reverse. If people started commenting that bitcoin is falling to $5500 or $3000" it means the time to buy and I have followed this simple strategy in trading and it seems the best investment strategy that follows professional's stocks investors trading principles. I will like you to share your stake on this so we can all learn.
