For early adopters who stepped in few years ago and have 100x profit it's just a matter of closing their eyes. For newcomers the risk is a magnitude larger since buying even a single Bitcoin is expensive. Still, some people say Bitcoin can go to $200,000 or even beyond. If that's true buying and closing your eyes is the best strategy no matter how hard it is.
I mean the amount of risk per Bitcoin whether it's whole or fractional.
If you take the market cap into account it takes a lot more money to go from $8000 to $200,000 than from $320 to $8000. It's harder, therefore less probable and therefore has a higher risk.
After all, Bitcoin was a fringe technology that has been labelled as a scam and ponzi left and right for years.
Now that Bitcoin is out of that storm and actually backed up by many very prominent figures it will be much easier for it to reach its potential, which is well beyond $200k per coin.
