The post gave a good example of the risk associated with real estate that was never envisaged. That is to show that even though Bitcoin is erroneously assumed to be risky and real estate safer, the reverse might actually be the case.
And nothing is risk-free. Every investment people do carry some kind of risks. Some carries more some carries less. And when it comes to holding Bitcoin for a longer period of time, how one can be sure that nothing will happen in that given time? We have to accept the risks and invest what we feel like is the best. Technically, not theoretically. You never know if you don't try.
The higher the profit, the higher the risk, there is no investment that is super safe and highly profitable. If bitcoin is really so safe that there is no such risk, I wonder if OP would sell all his assets to invest it all in bitcoin? Because if he is sure about bitcoin there is no risk then he should sell his house and invest in bitcoin then he will have 3 houses, LOL.
