It`s looks like a promising partnership,but that doesn`t mean that cryptocurrency trading will be accepted by Wall Street.You title is a bit misleading,OP.Bringing more institutional investors into the cryptocurrency market will make the crypto prices to skyrocket,but i`m not so sure that the US authorities will allow more institutional investors to diversify their portfolios with cryptocurrencies.
It is possible but for sure their will be more regulations that will be implemented. If coinbase reached the wallstreet, it would be good and bad. Good because the price will skyrocket, Bad because we will see more a lot of manipulations.
