The teams come in front or stay anonymous based on the nature of the project and the field they are going to serve.
Satoshi was determined from start to keep his anonymity but many of the core developers and proponents of bitcoin are know to public. Most of privacy based coins team are also anonymous while some have come forward to advertise and promote it.
But for every service related tokens like Ethereum and others, it's better for the team to come forward and take and share ideas for the development of the project rather than stay behind anonymous curtain.

I guess it's all about increasing the adoption of the CCP coin in China. But nevertheless, the technological advancement of the party and the mass adoption and use trial would be a good experience for every of the cryptocurrency. They may never outsource the underlying technology but others can watch and find what problems they faced and what solutions they implemented and try to mirror that with any of the options they can find. It's overall a positive move for blockchain technology.

Defi itself is not a high risk investment but scams and ponzi under the cover of Defi are risk.
There is risk of some loopholes or exploit on code in Defi but such issues occurs with every financial projects be it centralized exchange or decentralized one. But if they go through internal and external audit as well encourage white hat hackers to penetrate test it, Defi would be a much more secure option than any centralized finance.

You could call it a golden year for ICO but you can't say the same for crypto. Crypto are still in it's early development phase and they have still a large market to cover. The pump and the subsequent dump destroyed the way projects raised funds and that's for good. As of good cryptocurrency themselves, bitcoin has nearly reached 14K and they'll soon hit their all time high again and this time more sustainably. And again price doesn't make every coin good or bad.

This signifies that the experts and technicians involved there believes blockchain based crypto are the best form of currency (value vouchers). They are easy and quick and there are no problems like faking currency or any costs involved in printing and reprinting bills. The supply and flow of the currency could also be easily monitored by the central authority and if they have specific address assigned to people, they'd know whom the money is going from whom. That's both fascinating and scary.

Though Defi hype may be faded, defi are here to stay. They provide a solution to a great lot of problems concerned with central entity. But with the rise in popularity, they are also becoming a popular target for hackers and exploiters to siphon out and steal coins from the smart contract or users. Defi's should be very sensitive in such maters and test everyway the codes and be sure it doesn't contains any loopholes before releasing it to the platform.
You have listed almost all of the best Defis but other popular ones and hot at the moment are Aave and Sushiswap.

It would make it easier for them to deal with cryptocurrency and maybe evade some taxes. Corporates are attracted towards blockchain based coins as they fear of missing out and losing their market. But not only are they efficient for the corporates, it would also make it lot easier for users and advertisers. More efficiency and more competition would come back as a value to users.

Truly said. You can hold bitcoin and some altcoins for a long term if you believe they'd be much bullish in the future.
But if you still want to take the risk for a greater reward, don't just jump 100% on a new coin. However promising it may look, diversify your portfolio with different types of coins. Don't put more than 50% on the same coin.

Don't miss it again and again. Experts agree that bitcoin could be traded at a lot more price than it is now. Bitcoin was $6629 on April 12, 2020 while it's 13,400 at the moment. It's more than doubled in six months. That was the recent golden opportunity missed. There are many people who bought bitcoin at hundreds and sold at thousand yet missed out on the run to the price of tens of thousand. So, it all about what part you look at. There would be many more such opportunity but you should believe in bitcoin in order to get advantage of it.

The team is giving out more and more info and I guess it was not from an insider.
They claim it were from an exploit that was done "by manipulating stablecoin prices on Curve Finance, another DeFi protocol that Harvest Finance contracts interact with."
They have pointed out some addresses on twitter who were involved in casing out the coins and have asked help from prominent exchanges to track and prevent coins of those address being converted or withdrawn to other coins.

Though we often compare bitcoin to fiat, bitcoin is still not the alternative of fiat. We compare them to show in what sectors is bitcoin superior to fiat but fiat too is superior on some sectors. I don't think bitcoin itself would ever be replace fiat but with other cryptocurrency around, fiat surely would have a difficult day ahead.
Fiat has been here since ancient times while bitcoin is just a decade old. Bitcoin is a promising future while fiat is still the integral part of our society.

For something to be ponzi, it would require new people to keep on joining and increasing their investment on it to make it run. But that has not been the case with Bitcoin. Bitcoins actually have value and you can buy products and services using bitcoin. Bitcoin doesn't goes on increasing in price either. It's price increases or decreases according to market. Bitcoin is limited in supply, with fixed amount of coins minted, they would circulate but no new bitcoin would be added. It makes bitcoin a less of ponzi than fiat currency.

It would have reached $20K without any of those but again payment giants accepting crypto trade would bring in millions of new investors to bitcoin and crypto. And with their limited support, users would be introduced with the best of crypto world and would have a favorable experience. Bitcoin would soon be on it's way for 20K.

Brad Garlinghouse, the CEO of Ripple had criticized US for their crypto regulatory laws and perception. And had threaten to move out if they don't change. It's not a long time so I guess they were already looking at alternative to move on. UK is surely a better option as crypto market is flourishing largely on Asia and Europe a London lies somewhat on the middle of everything.

This is a good news for both Paypal and Paxos. Increase in business without the conflict of interest. Could even be a good news for Paypal user depending on what commission both of these companies take. Even if it's on a higher side, people would cheerfully use it as it would bring convenience and security to buying of crypto. I was frightened of thinking how Paypal are going to handle crypto, but with Paxos, I believe it would be lot better.

One of the reason for it is bounty managers themselves are not professional enough. When there are rookie bounty manager running a bounty, they are ready to compromise in most things. And another reason is greed, the once popular bounty manager atriz saw himself fall from fame just because he thought it was good to keep promoting a scam even after he'd realized it is. A professional bounty manager should always escrow the rewards wherever possible and stop promoting anything that's know to be a scam.

They are just starting. Adding them all at once would have technical difficulties and they won't be able to provide a support. Paypal is used by all sorts of people and you know how hard it's to make stupid people understand how crypto works. Even coinbase started with a few coins and now has plenty of them. Similar would be with Paypal, they are just testing how it would turn out and if they find it's profitable, they'll bring in more and more coins.

This year has been great for bitcoin and every of the metrics points out to bright future for bitcoin.
Decrease in fresh minted coins, institutional investors buying and hoarding of bitcoin, many business accepting bitcoin as a payment, payment processors making crypto trade-able and transferable. Many platforms, dapps and defi locking/freezing bitcoin to issue bitcoin backed token to facilitate trade. These various reasons are making bitcoin adoption and use popular and with lesser of those coins out their in supply and ever increasing demand, we'd soon see a rise in price for bitcoin.

The news is the prime reason for current price hike in the market specially for Bitcoin and Ethereum. Bitcoin broke the 13K barrier after quite a time while Ethereum's rise has been more significant in last 24 hours though they are much less than they were a week ago.
The news itself is a good one as Paypal being arguably the largest online payment system, would bring a lot of new customers to crypto and they'll open a new market. Paypal used to ban merchants for using crypto payments and often reversed the transaction on dispute involving crypto. Now it would be another challenge for them to track all the disputes arising from crypto trading.

I don't believe in this mafia style social work. They are not just hackers but criminals who used extortion to obtain the funds they are donating with.
Such activities and people should not be encouraged. Though they are acting as the good person here, they have done more harm to people.
Anonymous donations should not be stopped just because some criminals tried to send in donations. It would be better if that fund be used to compensate the victims of the Darkside hackers extortion.
