The price of the bitcoin a year ago around $300 and now the price has reached $2500, if I buy 1000 btc then I get profit 2200x1000 = $220.000, proved that bitcoin made many people rich.
That's a good calculation. Lot many people as well users of our forum might be using bitcoin when it was around $300, but none could have thought that the price could peak this high. Their ignorance now make them feel, because if they have considered it with trust, they could have got richer by now.
