I think that we all are in here for the same, but some of us use bitcoins for other kind of purposes.
But bitcoin is safe if you know how to take care of yours, if you use a bad wallet you are probably going to be hacked, it is upto you.
and bitcoin is much more safer than other investments, it depends on how are you looking at it.
True , the safety of our investments does not solely rely on bitcoin and its security system but to ourselves by being knowledgeable to possible threats and safety precautions for our wallet and account details. I think this goes to anything with money involve and specially in your investments, knowledge helps us discern what would threaten or make our investments profitable.
