If all planet will suffer from a strong EMP for some reason, then every electronic equipment would be destroyed, including Bitcoin network. Then at least for first time you wouldn`t be able to transfer your bitcoins

Sometimes I am making mistakes, but I am trying now just forget about market and cryptocurrencies during corrections

I think it could be, but only in a few years. Bitcoin still very strong and Ethereum have tough times even now

Not a bad idea. Litecoin is really a strong coin with good team and shiny future

In my opinion altcoins will always give more profit than main currencies with high capitalisation, so yes of course.

Real money will live long in any case. Even if all people will use cryptocurrencies, paper money will still worth something
