As far as making early investors rich, it's their advantage, they see Bitcoin's potential and it was realized in 2017, but we don't have to blame them though.
People thinking like that guy are dumb and short sighted. You have to follow what smart money is doing, and they are accumulating even at current levels preparing for the next leg up.
If you worry about making early investors rich then you can't invest in anything, because by that logic you're always too late, whether it's a stock, property, bar of gold, an artwork, a watch, and so forth.
And then we should ask that guy what his definition of rich is. The amount he thinks you need to be rich might be pocket change for others. People here never fail to surprise me with their stupidity.
