If bitcoin have weak security, i'm sure by now bitcoin would be controlled by government or dead.
Bitcoin is still alive is the proof that bitcoin network is really strong. Most bitcoin stolen/lost usually because user fault or 3rd party service bug anyway

I secondly agree with you....bitcoin is still on and growing stronger..population keeps increasing of those using it
I agree with your statement, bitcoin will be stronger if more people use it. bitcoin is also not exposed to great effect if global economic conditions deteriorate, and the security of bitcoin was better than fiat.
