Yesterday, Bitcoin has reached $18,000, which is close to the previous 2017 ATH. It shows the importance of Bitcoin after ATH in 2017, then suddenly collapsed, and is now back to catch up and even surpass its ATH. Bitcoin is indeed valuable, and the demand for it continues to grow. Some large companies are now adopting and allowing the buying and selling of cryptocurrencies like Paypal and Square. Now, not only big companies but also millionaires want to buy and use cryptocurrency. I think nothing can stop the continued growth of Bitcoin adoption.
