Yesterday at around 7:00 PM North America eastern time bitcoin passed $13,000 for the first time in almost 3 years. Which means bitcoin passed both $12k and 13k in about a day, but right after it went back down but the chances are good that it will go back up.
That proves how risky bitcoin is because this time it went up very fast but it could go down just as fast. So if you buy bitcoin only put in money that you are willing to lose.
