I can't share a link because I'm new to the forum. If you need the source, search the line of first message on internet. Im worried about bitcoin because wall street can be manipulate Bitcoin in the next years. Creating chaos by selling non-existent bitcoins only in the form of a contract. This is against the very nature of bitcoin and can turn everything upside down. Although it seems to be positive in the short term.
If all it takes to stop Bitcoin is to trade Bitcoin derivatives on traditional platforms, then Bitcoin isn't as resilient, or like some people say "antifragile", as some people though. But I don't believe that neither the Wall Street traders are going to manipulate it any more than the current crypto players are doing so, or that this would cause some irreparable harm. All the additional liquidity can offset the new manipulation, if there will be such thing, so it could be a net positive for Bitcoin markets.
