Bitcoin has had phenomenal growth in its price and MCap since inception. If we exclude other cryptoassets, Bitcoin has been the best performing asset in the world every year since 2009 through to December 2017 with the exception of 2014. It has beaten all global currencies, equities, commodities, bonds, ETFs, real estate throughout that period. Bubbles are by definition short-lived, they do not keep bubbling for eight years.
No coin will go up forever, even Bitcoin has very good days, and then some really rough ones. The crypto space is ever-changing and evolving, with new opportunities coming up every day. If you believe in a coin, holding it for long-term returns is a good approach, but if you are looking to make money by trading, you cannot have emotional attachments with any coin.
No, the successful trader is not me. I’ve gotten lucky a few times and I’m still refining and trying out strategies; on the other hand, I’m part of communities of people who trade on a daily basis to grow their portfolios, and while some of the results can be attributed to luck, a majority of it is based on fundamentals, good habits, and experience.
