Winning a lottery is very rare, and your odds of winning are 1 in 14 million, which is close to impossible, but still, there are lucky people who win it, so you still have a chance to win a lottery. The less risk we see, the less profit or money we gain—that's how it works. Bitcoin has a higher risk, but it also has a higher return; it is entirely up to you whether you want to take that risk or not. In life, we really need to take risks to be successful, but when we lose, let's just treat it as a lesson and learn from it.
