I'm not quite sure that these financial groups are aiming to help bitcoin grow in any way; the growth of bitcoin if anything hurts the influence these institutions have. If anything, they'll try to manipulate the price and seek to have their own trading bots go at it. seeing as how bitcoin is fairly more volatile as an asset compared to most stocks, they stand to make a pretty large amount if they are able to assert any control over the price.
They probably aren't, but they probably realize it's inevitable anyway, which is why they're going to enter in the first place. Either way, the end result is the same: more money in the market, and a more bullish case for investors.
sure, it's more money in the market and more trade volume, but price manipulation is a very real thing, and once they learn they can manipulate the price with their billions, its just a matter of time before they start going further and further. for example, who knows if these groups arent planning their own crypto mining facilities? If bitcoin becomes big enough to seriously threaten the hold the banks have over the financial world, im sure they wouldn't have a problem finding the money to go as far as starting their own mines and attempting to start chaos in the network, possibly even go as far as a 51% attack (unlikely, but definitely possible).
Right, the increasing adoption of bitcoin and being considered a digital gold means bitcoin is here to stay and for financial institutions to survive they have to adopt it. For me, bitcoin will have a massive increase these year considering that it is still half way through the year and bitcoin price is now at a five digit mark, corrections are always there but I guess $20,000 price of bitcoin will be very possible to happen.
It's not a matter of the financial institutions surviving; they're just testing the waters right now. Currently, bitcoin is starting to take off to the point where these institutions can't just ignore it anymore. give it time, im personally of the opinion that these institutions will try to kill bitcoin off once they deem it a threat.
