Being rich with bitcoin is not a silly pipedream anymore as the price continues to soar and break all time highs. If you have been holding even 10 bitcoins when the price was still at $200, you would have made over six times that amount right now. That kind of growth is hard to come by in any other kind of investment, even the ones with the highest risks involved.
Along with the growth of the bitcoin price, everything else is growing. So it will not be very good to get rich, you can only earn a little.
