If you want anything in life, you need to give something up or at least be at the risk of losing something. Without the chance of losing, the reward won't be worth it.
Similar is the case with bitcoin. We have seen the cryptocurrency go through so many stages, it has seen immense attention, people have gone crazy buying it, but we also have seen a stage where the cryptocurrency has gone through major backlash and has dipped too low. All this is what makes investing in bitcoin so interesting and addictive, you have a chance of losing your money but you could also get immense rewards from the same.
