This was inevitable. It is possible to trade between crypto- and fiat currencies. 99% of fiat capital is in the hands of 1% of the global population. Those people are heavily involved in the financial sector. Therefore is no point in rejoicing or cringing over this. The financial sector will always move towards opportunities for gain. So their entry into crypto is the only possible event while crypto is in fact on the rise.
The only thing I take from this piece is the fact that crypto can no longer be ignored or laughed away. It's here to stay, with fundamentals that outperform fiat on every level, given that technical limitations are only temporary.
