If someone is willing to speculate (let's say suspecting BTC will burst, but not for a while yet), and that person is using spare money and cashing out after a week or two even, how are they a sucker? Any person who's asked me about getting some Bitcoin has seemed perfectly aware of what could happen. I got BTC at $900 (now approaching $12k). First got Monero at $70, and it's close to $250. Maybe I'll pick the wrong time to sell, but it's a risk I'm aware of. I've lost much more money on speculative stocks (backed by actual businesses with real assets) than I have put into this. For anyone throwing in $100 just to be part of the adventure, I'd bet they've spent more than that on a single night getting drunk at the bar.
