I dont think that Bitcoin is instant way to get rich, it is just like the other currencies, need hard work to earn it and not so easy. You can get rich if you hold good amount for some years and if the price rise highly in this period
We need hard work to earn Bitcoin, the price that keep increasing everyday will make us feel that we are become rich instanly. The price of Bitcoin that always go up is such as passive income for us. Because our money grow even we aren't doing anything.
if you have a lot of money and you invest your money in bitcoin then you can thinking that bitcoin is instant way to get rich because you only need to buy huge bitcoin amount and then save it in the wallet. you can sell when the price is increase so this will make you rich. but for people which don't have money then they must work to earn bitcoin and it is a long journey to that person and it is not instant way to get rich but soon he can be the richest person in their city.
