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.
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.
