In some cases, individuals tend to have multiple Bitcoin addresses to send and receive transactions. Interestingly, the growing number is potentially driven by the need by some investors to handle each Bitcoin transaction on a new address as part of maintaining privacy. Number of bitcoin wallets Bitcoin is not innocuous. Transactions are processed by “miners” using massive amounts of computing power in return for rewards in the form of Bitcoin. By some estimates, the Bitcoin network consumes as much energy as entire countries like Argentina and Norway, not to mention the mountains of electronic waste from specialized machines used for such mining operations that burn out rapidly.

Since hot wallets are connected to the internet, they are more vulnerable to hacking and other security risks compared to cold wallets, which are offline and therefore more secure. As such, it is important to take precautions to secure a hot wallet, such as using strong passwords and two-factor authentication, and not keeping large amounts of cryptocurrency in it for extended periods of time. BTC definition: What is Bitcoin? There may be another reason why some wallets are never be touched again - their rightful owners are deceased. If someone has never left instructions on how to access their wallet, which is very likely as doing so would immediately compromise their wallet security, then when they die, there is a high chance their fortune would be stranded in their wallet. 
George Soros' fund owns bitcoin, CEO confirms
The technology is not without risks. Facebook plans to issue its own cryptocurrency called Diem intended to make digital payments easier. Unlike Bitcoin, Diem would be fully backed by reserves of U.S. dollars or other major currencies, ensuring stable value. But, as with its other ostensibly high-minded initiatives, Facebook can hardly be trusted to put the public’s welfare above its own. The prospect of multinational corporations one day issuing their own unbacked cryptocurrencies worldwide is deeply disquieting. Such currencies won’t threaten the U.S. dollar, but could wipe out the currencies of smaller and less developed countries. 2. Cameron and Tyler Winklevoss "If my bitcoin keys are somehow connected to the internet, then, as I'm sleeping, there could be a hacker that's trying to get access to my keys," Lewis says. That's why hot wallets, or those connected to the internet, are considered to be much more risky than cold wallets.
Who owns majority of bitcoin
The mining reward is structured to decrease after every 210,000 mined blocks. Since the combination of block difficulty and solving time is somewhere around ten minutes, therefore, it takes around 4 years to reach the halving point. Based on these calculations, every four years, the reward is cut into half until there is essentially no reward for bitcoins. That is, in about 120 years from now, in the year 2140, the nodes will have effectively mined all 21 million bitcoins reaching the maximum supply. Who owns all the Bitcoins? According to most common estimates, it is Satoshi Nakamoto, the anonymous creator of BTC, who has the largest Bitcoin holdings in the world. However, we don’t really know who this person (or group of people) is. Therefore, it is currently impossible to answer the question: Who owns the most Bitcoin?
