In any case, you need to watch the development of events in the cryptocurrency market and in relation to a specific project. You can keep Bitcoin in your wallets and wait all your life for the moment when Bitcoin reaches $ 100,000 or 1 million. And you can sell and buy again during this time several times, while making a lot of money. As an example, you can take 2020, and whoever bought bitcoin at the beginning of the year earned a lot today.
