I think this is fundamentally good. A lot of people started investing their money in Bitcoin. This means that the level of trust in Bitcoin is getting higher. If you have money more likely to buy now for the future is not to lose. But if you look at the current technicals, maybe he will be corrected again at the price of $ 17,500. Maybe then is the perfect time to buy back. IMO

I don't need  prediction to determine that the price will rise and then fall. Is there anything else?

Isn't it already a global asset? Bitcoin was always a global asset but these big guys have now started to enter into this market. Hopefully, this bull run will not be similar to 2017. If the big pocket investors invest in bitcoin, the current price level will find some support at 19000 USD.

I know a lot of people are still very cautious about entering into bitcoin right at this moment because of their past experience. Hopefully, this time it will be different!

Bitcoin is already a global asset,it was a global asset right from the beginning,there's no need to evolve into such asset.Bitcoin was never a national/local asset.
Can you mention a few "big guys from Wall Street",who are currently getting involved in Bitcoin?
I don't know about any Wall Street "big sharks" buying BTC right now.Maybe they are keeping their buying process confidential.

The rise in the price of bitcoin in 2020 is very different from the rise in the price of bitcoin in 2017. 

2021-2025 is the time of transformation of the global financial system.  The dollar is losing its function as the world's reserve currency (gold lost this function even earlier).  2021-2025 is the time of the development of central bank currencies (CBDC) and the liquidation of commercial banks.  At the same time, CBDCs do not provide for the use of offshore companies.  Also, CBDC does not provide for the opening of deposit accounts for individuals and legal entities. 

In this situation, Bitcoin becomes a reasonable alternative, a very important financial instrument, an attractive deflationary asset.

Expecting big volatility

It is all fun and games until every rich people go for this and hodl. I do not like that they all take notcie of this, I am sort of gatekeeping. This attention will lead to the interest of the government to scrutinize bitcoin and other cryptocurrency, I believe this will be the reason that the purpose of bitcoin and other digital currency will change drastically.

More and more number of large scale companies are investing on bitcoin. Already Wall Street people might've invested on bitcoin, but those aren't revealed to the outer world. Now slowly things are getting revealed, and the same is helping with the growth of bitcoin in terms of usage, adoption and as payment on more number of stores.

This is all great positive sentiment that has been going on for some time now. The only few hurdles remaining are:

1. How do US regulators treat it with the change in administration. There has already been a talk about regulations to ensure that "Wallet providers" don't treat people differently like traditional banks have when it comes to access to credit. Just looks like an excuse to get KYC from wallet software providers. Running your own node may become essential for those who desist KYC.

2. IF bitcoin gains such prominence, it remains to be seen that what political actors want to do about the mining dominance of Chinese ASIC hardware.
