Saving bitcoins for the future it's the best idea, if you can afford it then do it (at least try to save) and i hope that in the near future the price will be increased much more than it is now.
Absoletely not agreed
Blockchaintechnology within banks and companies is a matter of a few years, months even. Once that happens, all the sheeple follow and bitcoin will crash IMO, I hope not, but the little devil on my shoulder keeps shouting that it will 
The thing is, to gain consumer trust with big dollars, the banks will need trust worthy miners. Blockchains most impressive feat after being developed is the sheer amount of hashing power that is being put out and the level of trust that its "network" generates. The miners are a fundamental part of the technology and the ideals behind it. I would like to believe the banking system realizes this right now, as it will help with the going mainstream part that it has had such trouble with. This technology is going to make them a mess load of money and it will also allow for a lot of change in this world.
