LONDON (Reuters) - PayPal Holdings Inc joined the cryptocurrency market on Wednesday, allowing customers to buy, sell and hold bitcoin and other virtual coins using the U.S. digital payments company’s online wallets.

PayPal customers will also be able to use cryptocurrencies to shop at the 26 million merchants on its network starting in early 2021, the company said in a statement.

PayPal hopes the service will encourage global use of virtual coins and prepare its network for new digital currencies that may be developed by central banks and corporations, President and Chief Executive Dan Schulman said in an interview.

“We are working with central banks and thinking of all forms of digital currencies and how PayPal can play a role,” he said.

U.S. account holders will be able to buy, sell and hold cryptocurrencies in their PayPal wallets over the coming weeks, the company said. It plans to expand to Venmo and some countries in the first half of 2021.

Other mainstream fintech companies, such as mobile payments provider Square Inc and stock trading app firm Robinhood Markets Inc, allow users to buy and sell cryptocurrencies, but PayPal’s launch is noteworthy given its vast reach.

The company, based in San Jose, California, has 346 million active accounts around the world and processed $222 billion in payments in the second quarter.

Cryptocurrencies tend to be volatile, making them attractive to speculators, but a lot less appealing to merchants and shoppers. Transactions have been slower and more costly than other mainstream payment systems.

Cryptocurrency payments on PayPal will be settled using fiat currencies, such as the U.S. dollar, meaning merchants will not receive payments in virtual coins, the company said.

Many central banks around the world have expressed their intention to develop digital versions of their currencies in the coming years, while Facebook Inc-led the creation of a cryptocurrency project called Libra in 2019. PayPal was a founding member but dropped out after a few months.

PayPal, which has secured the first conditional cryptocurrency license from the New York State Department of Financial Services, will initially allow purchases of bitcoin and other cryptocurrencies called ethereum, bitcoin cash and litecoin, it said. It partners with Paxos Trust Company to offer the service.

I think you're mistaken.
If you want something that signs messages in general use GPG. It would be an extremely bad practice to come up with some novel cryptosystem just to sign messages when established audited and mature alternatives exists.

Bitcoin uses a novel cryptosystem for signing transactions called Bitcoin Script which allows all sorts of complex constraints on the signatures.
each implementation of bitcoin should have a way of producing and verifying ECDSA signatures and work with scripts to some extent (usually standard ones only) but they don't have to have the flags used in bitcoin core specially when it comes to message verification. for example none of these exist in SPV clients such as Electrum so their code has to significantly change if they wanted to implement this I.P.:

also these flags are used during block verification and most of them are there for backward compatibility (eg. whether BIP-66 is enabled to use DERSIG or BIP-112 for OP_CSV), i don't see why they should be used in a message signature verification.

not to mention that certain things from bitcoin scripts can not even be imported into message verification. some are addressing malleability issues, some OP codes such as those involving locktimes cause a lot of problems as there is no transaction or block to use for verification, the "signature" that is popped from the stack in transaction during script evaluation has a sighash flag which makes no sense in a message since there is no txout/ins to sign based on that,...

Yucky for the spec to be described in terms of those flags which are presumably not adequately documented.

But the behaviour they signify has to be handled correctly to use generic Bitcoin addresses to process messages.

I wonder if you would support a version of BIP322 which:

1. Required all standardness rules be obeyed (and allowed as an "extension" to validate such signatures, somewhere cordoned off at the end of the BIP where
2. Specified what these standardness rules were/meant
3. Allowed implementations to return "inconclusive" for scripts they did not understand, while still permitting them to implement only templates if they really

The first two rules would let you use off-the-shelf Minscript software (such as this implementation in Python to support all widely used scripts except HTLCs, so even if you did not write a full BIP-322 verifier (which would require libbitcoinconsensus or Core) you would still be able to support a wide array of real-world usecases.
Short term speaking it's impossible to figure out, but we have enough empirical evidence that the price always favors the long term, and based on that you can long the market without any problems. If people did just that instead of blindly betting against the short term market they would be a whole lot wealthier right now. It even applies to stocks -- if you open a long term long position you are pretty much guaranteed to see the value go up. It doesn't require people to be a rocket scientist, ask Warren Buffett, it's his favorite way of investing. He's also not shy of using a very low leverage multiplier to generate even higher gains....

as usual whenever the price falls a lot we have all news channels talking about bitcoin. in a few weeks we will have more news with titles of how bitcoin is just falling, when we will see the bottom, we found the bottom, will fall down of $ 5000. and if prices increase then we will have many analysts saying that the price will reach $ 40,000, other more daring analysts will say that the price will rise to $250,000. and the argument is input of institutional investors. This has already become a very predictable novel
