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.
they're not the same mate, investment is holding and trading is buy low and sell high.. Perhaps yes both way is almost the same but you should know the difference, especially when it comes trading because the risk is higher than investment, if i were make more research for more information, infact all the information can easily be seen in the internet. So don't hesitate to do such way always if you have more questions about such things..
