Alright, although this isn't FUD. When you invest in Bitcoin, you aren't guaranteed a return. as was once said by Benjamin Franklin "Nothing in life is guaranteed, but deaths, and taxes". That's true. Bitcoin is not a get rich quick scheme, and has a chance to not increase in value like it has in history. Remember, correlation isn't causation too, so when looking at charts, and speculating about price be careful.
What you are guaranteed with Bitcoin: No third party involvement, the chance to be your own bank, take care of your own security, determine what fee you want to pay (although, somewhat restricted by miners not including it in the block if it's too low), and freedom of spending your money, without your bank preventing you. If you want to use it for gambling, you can use it for gambling. If you want to use it to pay for groceries, there's services out there that allows that. If you want to pay for your rent with it, you'll have to contact your landlord.
Ultimately, what Bitcoin does provide is freedom. No, not the illusion of freedom that we've all become accustomed too, but proper freedom over your money. As above, you still have to pay your taxes, but other than that no one can tell you how to manage it or what to use it for. Obviously, a barring any illegal activity, but I think that goes without saying for the majority here.
Only wise investors seem to buy at a time like this.
Hmm, I wouldn't put it that way. I'd say those with less risk tolerance invest in times like this or perhaps a more biased view, would be those that believe in what Bitcoin stands for, rather than being wise.
