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 $200, you would have made over six times that amount right now. That kind of growth is hard to come by in any other kind of investment, even the ones with the highest risks involved.
Along with the growth of the bitcoin price, everything else is growing. So it will not be very good to get rich, you can only earn a little.
That's a weird statement...
First of all, not everything else is growing, some, if not most traditional fiat currencies are losing value. Other stocks or commodities that are growing are just not growing as fast as bitcoin, so that's something you left out.
Even an average person could still get rich with Bitcoin, just invest 10 to 50k and sell after another 500$ price increase. I doubt that it would take more than a year.
This is what some people dont take in to account, stocks can grow and give you profits, but nothing is growing like crypto right now, you can earn a lot by just holding, someone that bought 10k worth of bitcoin when it was worth 200 dollars some years ago bought 50BTC, by that investment he could get 80k if he sell his bitcoin right now.
