...- if the big banks really start offering market-making for cryptocurrencies...
That's the point, banks do not want to use our bitcoin, they are looking for "all the cake", but IMHO they are not so intelligent, they did not realize that bitcoin can not be emulated, not at least with the security with the current hashrate power, so, or they jump into our board or they will have many complications if they want to use it.
The only downside is that many institutional investors are legally bound to invest in certain asset classes. Unfortunately, when these guidelines were created
cryptocurrency wasn´t even invented yet.
Yes, but don't worry, things could change especially if they know that could take advantage over it
