Another person here interested in Bitcoin investment

I think there are lots of newbies like me attracted by the +1800 USD rise this month.
IMO, it is an interesting investment if you can afford to lose the money. And if it becomes the future of economy, it will have a huge increase potential !
However, I fear that if people just invest into it and never spend the money, it will make the Bitcoin economy to fall into a deflationary spiral, with a potentially harmful effect for it..
