On January 3, 2021, Bitcoin reached an all-time high of $34,608. This is an incredible gain over the value of less than $0.01 in early 2010. The gain in the second half of 2020 was 252%, the last quarter 206% and even 70%+ for December.
Bitcoin has attracted a lot of attention because of the high price. More people are buying the cryptocurrency than ever before. Unfortunately, there is quite a scarcity of Bitcoin. As of this date, there are only about 18 million Bitcoin units available. Demand for them pushes up the price. More people coming in need to buy more units, but they aren't all that common.
It is quite a concern that the price has risen too high too fast. There is the real possibility that a price correction can happen in 2021. This has been seen before. If the price does drop significantly, it may be a better buying opportunity than buying at the all-time high. Be careful and only invest money in Bitcoin that you can afford to lose.
