She is lucky to still have access to the wallet and her luck is multiplied by accessing the wallet when the BTC price is quite high although not the highest.
There are many stories out there of how they became surprised that their crypto asset in BTC, had multiplied in value in USD due to the increase in the price of BTC, sometimes not knowing how valuable btc could make a profit.
Her luck lies in the fact that they had no idea what bitcoin was and forgot about it for many years. If this had not happened, then she would have sold her btc long ago for a lower price. The plot in such stories is almost always the same: people forgot about bitcoin, remembered many years later and found an impressive amount in their wallet. This is what allows you to increase savings at btc. From which the conclusion suggests itself that if there is a goal to earn on bitcoin, then you need to buy it and put it off for many years, so as not to succumb to the temptation to sell at a low price. As you can see, even $50 can grow significantly and even now it is not too late to invest such a modest amount for years to come.
