we all know that Bitcoin is so broad that coming to crash is so minimal, but the big question is  what if it crash?

it is so obvious that majority of the world is totally dependable on Bitcoin.
but I think that in anything we do we should try as much as having a plan b, there is nothing wrong if we invest in other business as plan b.
for example I have seen most men who are international staffs in an oil companies taking a huge amount of money at every end of the month not knowing that nothing last forever more especially money.
so am on the opinion that every Bitcoin miner should have a plan b of investing in other business to avoid the story that touch.
