Dunno if this is a genuine post or another cook up story to attract merits, but I'm going to say this to you anyways. In as much as I'm pro Bitcoin, I would not advice anyone to sell his/her valuable properties in order to invest in Bitcoin. It's volatile asset and your investment could appreciate or plummet. Also, Bitcoin investment is not a get rich quick scheme, and it take time. Do you even have knowledge of the market? Do you think your dad will be patient enough to wait for the value of Bitcoin to appreciate in order to take profit?
If they sell cows for a living, well, I'm pretty sure they are used to be patient because a cow doesn't grow in a week so I wouldn't worry about patience in this specific case. And if by any change the father becomes impatience, again, the son has the perfect example in front of their own eyes.
I would suggest the OP to save a little money in case BTC goes down, don't buy all at once, keep some emergency funds ready to be invested.
