I think it's better to save the money to buy her something more tangible such as gold and also the home. because if you invest here you will be quite difficult to sell the goods and also every time will be ascending. If I were you I choose to invest like this
Unless you buy the goods into those traditional form.
Remember there was a guy who bought a house for 100 btcs or some ridiculous amount. I know most home buyers wouldnt take the plunge unless they knew the price of bitcoin was back in the 1000`s.
I'm ready to pay 100 btc for a house, please sell it to me
Looking at the price rate of today, I would get the home in 20526.00 US Dollar which is a pretty sweet deal, so please I am waiting, where you at
Still can't believe who bought a home at 100
BTC when 1
BTC was 1000$, he bought a home for 1000 x 100= 100,000$, which is not as sweet a deal now, is it?
