More than a decade of career in the cryptocurrency industry has almost eaten up all the profits of my positions. The truth is simple. If you firmly stick to this kind of trading system, this system will become your cash machine over time. I am one of the earliest people in China to play Bitcoin BTC. I have been advocating Bitcoin BTC since 2011, but I got off the train early after playing for a short time. Later, I played altcoins for a while and made a little money! At most, I had 4-digit Bitcoin BTC! If it had been kept until now, it would be worth about 10 digits of RMB. But most of them were sold after making dozens of times the profit, but there was still a small amount left that was not sold. The reason for not selling it was also very simple. The small amount was too small and I didn t look down on it, so I just left it in the exchange and didn t care about it. But even if it was a small amount, it was a 3-digit Bitcoin BTC. Or let me put it more bluntly, this Bitcoin BTC small amount that I didn t look down on at the beginning is now close to 9 digits of RMB.
