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.
Yes because there is no shortcut in success! even millionaire become success because of there hard work. Bitcoin can be a key to instant success if you have investment in the past and that could be worth of millions now. But still at this time is not to late for us to invest in bitcoin even if the market value now is to high! there are also some good alt-coin that are worth of investment too like ethereum because the price now is just small compare to bitcoin.
