From so many points of views, Bitcoin (BTC) trading is investing with the aim of making profit and making gain,I have understood it purpose and it is vulnerable to it's stakers.for one to stake means he/she is ready to profit or lose.
Got a little confused about the word stake but some users here tell that you might be referring to trader or investor. Yes, all investors know that there's a risk and he or she should be ready on what will happen that is why it is important that you should only invest what you can afford to lose not just in trading but in investment too. When you are going to invest to Bitcoin you should accept the fact that there's a big chance that you will lose your investment.
