Fly your flags! Let's hear from the bulls < and bears >
OK Boomer ------> DrStrange
PS I stand with Warren Buffet who declares Bitcoin and the rest of the crypto as "rat poison". I wouldn't buy any of these coins as an investment or for speculation. But I do have an open mind as to their potential for certain sorts of payments. < bitcoin looks pretty good as a way to pay ransom for example. > Not optimistic, but willing to see how things work out.
PPS Paul Krugman's piece this week regarding Crypto was pretty interesting to me.

Doc, I have been educating myself on this crypto thing a bit over the last few weeks. What is very "ok boomer" is that the majority of information is in youtube videos and sub-reddits - no sensible places where you can read a big pile of information, its more piecemeal. Just like with any other potential investment there is a plethora of believers and nay-sayers. Even in the crypto space there is a fight between believers in the various coins.
A great example are my two friends who are heavy into crypto:
- one is a Bitcoin bull (has 80% in Bitcoin and 20% in others but every 6 months or so, if the others overtake bitcoin, he rebalances back into Bitcoin). Note that he only goes into Bitcoin and never the other way
- the other has made a lot of money on Bitcoin but thinks it's not the future and has put his money in Ethereum and Cardano
Some people talk about Metcalfe's law and how it applies to crypto. Essentially the value of a network increases with the square of the number of nodes (or users for crypto). This bears out for everything from telephone lines to facebook.
So the first bull case is that the more people who get into crypto, the greater the value. Many coins have limited supply (Bitcoin is capped at 21 million) so linear growth in users results in a exponential growth in value. Bitcoin is analogous to gold. You can't take a gold brick and buy a car so its utility is similar and its main use is as a store of value. BTCmarket cap is currently $730B and launched in 2009.
The bear case for Bitcoin is that it's a huge energy hog. Its falling out of favour in places like China where they're burning lots of coal to run their bitcoin mines. This is similar to gold - miners dig more gold out of the ground to increase supply and they sell that gold to pay for their mining and to make a profit. Bitcoin works in the same way - the mining (validating transactions and maintaining the ledger) is rewarded in Bitcoin which they sell to pay their electricity bill and make a profit. The rewards from mining are through a "proof of work" model where the miner's computers have to solve a complex problem to win the right to validate the transactions and get the reward. Therefore people with larger mines will get more of the rewards. The key difference with gold is that if all the miners in the world stopped mining gold, the gold would still exist. If all the Bitcoin miners in the world stopped mining then there is no one left to maintain the ledger. And currently the bitcoin network consumes the same power as the whole of the Netherlands. It's a negligible fraction of this power consumption that's actually used to validate transactions, all the power is used to win the right to validate and get the reward.
Cardano is the 3rd largest coin by market cap and operates with a "proof of stake" model. Instead of doing complex calculations, holders "stake" their coin and deploy a server to buy a seat at the rewards table. The transaction validation and ledger activities go from staker to staker with rewards proportional to the amount of their stake. There's is no excess power used to win the right to the reward so it's very energy efficient which is the big bull case for Cardano at the moment. Cardano is trying to be the king and has first mover advantage in the low power consumption area. ADA (Cardano) went from nothing to $32B market cap to $3B and then to $50B currently. The swings are WILD and it's only been around for 3 years.
Ethereum is the 2nd largest coin by market cap and currently operates like bitcoin (proof of work) but is moving to a proof of stake model but with a fixed stake (currently 32 ETH). When this happens (in the next year or two) Ethereum may be the biggest network with the lower energy credentials. Ethereum also allows for deployment of things on top of the blockchain, allowing for things like smart contracts, decentralized finance and NTFs. ETH is currently $300B market cap and started in 2015.
Coming back to Metcalf's law - right now something like 100 million people on this planet own Bitcoin. That's nothing like the 2 billion users that facebook has. We're still in the very early stages of adoption and any one of the above coins or a new coin could overtake and become the dominant preferred crypto. Which one will be the winner? Not sure but the growth is exponential so even if you spread your bets, the winner will make up for it in returns given that it's still very early days.
