It's normal for Bitcoin prices to rise because this phase will definitely continue.
I've read it for this thread, and some say ETFs are the main factor, SEC regulations etc.
What is interesting about Bitcoin continuing to rise again is because Bitcoin has its own community to increase its price, such as investors, traders or several retail traders.
40,000 USD is quite an expensive value at the moment, but many media or experts in Bitcoin trading predict the price could exceed 125,000 USD. If it is true, up to 125,000 will be the latest All Time High and will be recorded in history.
