Mostly those rich people who bought bitcoin in a cheaper price and people who trust on bitcoin that are big time they are called also whales and those controlling the price in the market and have thousands of bitcoin.
They are so lucky and I really sometimes think why I am not rich as they are but I still have chance i am collecting money to buy some bitcoin so that same as those rich people later on I also will be one of them o will save it and sell at very high price. I am happy to have bitcoin in my life even for small number but the profit will be high.
They were not lucky, this is a thing that many believe and that is not true, those that invested in bitcoin early saw the almost infinite potential of the technology or they were looking for something like bitcoin to appear for some time, so we need to stop comparing ourselves to them and think about how to get more coins so when the value goes up we can get the benefits of that growth.
