well for me bitcoin is not a bad idea when you're retired after all.so better save your money for the future.i continue the bitcoin because there's a chance that migth bitcoin can grow more than spent my retirement money for vacation.
The comparison you make is bad - you are talking about investing your retirement money in bitcoin rather than spending your retirement money on vacation. The problem is - you shouldn't be spending your retirement money on a vacation in any case. Personally, I would be comfortable only with investing a small amount of my retirement fund in Bitcoin.
Exactly, you must know how to manage your money well. Remember that you was retired means that you will not get any salary now. If you are going to spend your money to vacation and there is an emergency comes where you can get now? We must always use our money in important things. We must budget if and do savings if we want to have some vacation.
