One of the pillars of Islam is going for holy pilgrimage (Hajj) I urge you to try your possible best to fulfill the dream of your mother going to Mecca, though it's a capital intensive project, however with proper planning via your investment in Bitcoin possibly before she clock 70 years the needed funds and travel expenses would be realized and hopefully if the price of Bitcoin pump massively to a new ATH all your invested asset would have yielded and earned you a reasonable profit which should be enough to cover all her pilgrimage expenses, I believe your aim and aspiration is very achievable with commitment and perseverance.
