If any government plans on banning bitcoin within their jurisdiction, I don't think that it would really be that effective since people would still find ways to utilize bitcoin and freely use it even though the government restricts it. Forcing something to the public isn't something that people would gladly accept. Bitcoin will still flourish even with restrictions.
The nature of bitcoin makes it hard for any government to try to take direct action against bitcoin, even if they attacked the miners the only thing that would do is to lower the difficulty and now everyone could mine bitcoin again, so it is a difficult challenge for them.
Bitcoin depends on one important aspect, and that's internet. If you want to hit Bitcoin real hard, then you as government should group up with other governments in order to block all access from and to everything that is Bitcoin related. It won't result in a full wipe out, but the effect will be felt on a massive scale. But I am glad that not every government sees Bitcoin as a high level threat. It considerably diminishes the chances of this to become reality.
So technically, its impossible to banned bitcoin because it will take gargantuan task for every government around the world to put a stop to any thing bitcoin related. But let say they successfully banned bitcoin globally, I think there will still be someone holding bitcoin, but has it has no value. Maybe they would hold in at some sort of memorabilia.
and hoping that one day it will be unbanned and will make fortunes in the bitcoin they kept.
Not just as a memorabilia but also for the purpose of "what if". It will not be "unbanned" but most likely people will find out how to use it without going to jail. Just in case people go back to using bitcoins and the market has pumped, they are going to earn some money out of it. Since at the point when every one has migrated from bitcoins to another coin the price per bitcoin will be really low anyway so investing in it wouldn't cost that much.

Attacking the miners will cost a lot of money and at the same time, it will cost some time. Since there are people that have invested millions of dollars for the purpose of bitcoin mining, they would have to built a mining farm that's better than the best ones we already have. And as time pass by, it will require even more money since the amount of investments for bitcoin mining is increasing and increasing.
