His first dream is to build a house with this retirement money. But right now in my country all the materials needed to build a house are very expensive so building a house right now can't be a good decision. And I don't feel safe keeping his pension money in the bank because earlier there was inflation in my country where some banks went bankrupt.
True, starching money in the bank for a long period is only a waste of asset and time as nothing profitable is attached at the end but if I should put myself In your old-boy should I would say you should let the old man breathe fresh air with his money by building for himself and family a place to call a home of his. There's no time the cost of things are going to get better or reduced not even building materials so people should always be ready to build the size of a house their money can afford for them, and I have the feeling that the old man's retirement benefit can afford him a good sizeable house looking at his years of service. Don't delve into the risk of crypto investment with another person's money despite your relationship with the person always make sure to use your own money and an amount you can overlook just in case. By so doing you have to owe anybody any explanation at anytime.
It's a good thing to provide flexibility for now. Older people especially have reached retirement age it is time for them to get a return for what they gave during their service in their youth and now it can be said that it is the harvest of what they planted before, it is not very ethical to put too much pressure on investing in bitcoin especially this has a fairly large level of risk.
Thinking about the future is good, but for old people in retirement, it's time for them to enjoy, not to start, even if it's not a problem for them to learn bitcoin, but that doesn't mean they have to get involved in it.
