Maybe it's riskier than usual but long term it's not at all risky. If you want to buy long term for the destruction of the current government-run butthead money then just buy a little every day. If you want to get in, make 20% and get out, then wait a week.
In the big picture, it's always good to buy bitcoin. The risk is just that if you don't time it perfectly you get less.
If you bought at the peak in 2011 at around 1200, you lost like 75% short term and now would have made that back plus about 300%
Now, if you bought at 1200, and again at 800, 600,400,250, 400again, 600 ..... you'd be filthy stinking rich right now, and that's like a worst case scenerio.
Call me crazy but I think the average person wouldn't like to have their money locked up for years, potentially losing 80% of it's value, if they can chose to wait and buy a bigger amount for less money later, after the bear market. The $1200 peak was in 2013 not 2011. I did buy right after the bubble popped for $600 per bitcoin in 2013 & I saw my investment go all the way down to $170 per bitcoin over the years. Only recently the price has gone up. I wish I would have sold then & I could have used that money for other things & just buy at $180. It's hard for me to understand how people don't see this...
