The CMC volume numbers show around 3% of all USDT trades in USD/USDT markets today, so that would be $0.03 in the analogy above.
- But I disagree that there's something nefarious going on : they're saying in no uncertain terms that they're playing the ponies with your money.
Do people understand they're being played? There's plenty of ignorance to go around. (cough bitconnect cough)
To my parents! The pic was taken near Gouda (yes, that Gouda).
Don't put the burden of Grand Success on your shoulders. You don't need to, you're not the one who's organising this. Focus on the thing you're arguably good at (because otherwise you wouldn't have been asked): making people excited about astronomy! If I went to such an event, my expectations would be "someone smart who tells about their field of study with excitement". Aim for that. Like, how the hell do we know all those things about the Earth and about our stars? It's weird for outsiders that you can look through a tube, make some calculations and predict a friggin' eclipse.
I think you're pretty close to how it actually works. I'll preface my explanation by saying that I'm doing this off the top of my head.
So you understand that the blockchain is a ledger, aka a record of the total history of a certain state. In the case of regular blockchains, the state that the ledger keeps track of is the amount of money in each wallet. It is a particular state in a particular wallet that forms the basic building block here. Now: "wallet" is a bit of a constrained term, as I tried to explain with my Ethereum explainer, because your "wallet" can also hold other states. "Account" is a better term, imo.
You can totally put the text "I AM THE LORD OF CRYPTO" on the blockchain if you want to. It would be a state that would be associated with your account. To associate a state with an account, you need to perform a change (from nothing to something). Those state changes are done by what are called "transactions". Again, terminology is a bit crappy, because "state changing function" is what's actually happening. But since it requires effort, you pay a small amount of money (in the form of gas) to get your state etched into the blockchain forever.
The Ethereum network (the combined set of all computers, aka nodes, that solve the sudokus) all then perform the state change that you have requested and have paid them for. The Ethereum protocol is the meta-code that allows or disallows your state changing functions. In the case of a regular wallet with Eth in it, the protocol for example has the rule that you can't spend more than you have. In the case of your self-absorbed text, there are no rules as to what to do with that text unless you specify so. For example, you can define it as "text that only I can change", just like Eth is money only you can access. (And by "you", I mean the person holding the account private key.)
Now here's the cool part: you can write your own bit of protocol that is understood by the Ethereum network. THIS is what the nerds call "smart contracts". So if you write your application (with your own logic and variables and functions) in the Ethereum programming/protocol language, everyone in the network and everyone connected to the Ethereum network can use your application. Your application code is saved on the blockchain as a very long piece of text. It has to be, because that makes it possible for every computer in the network to read, parse and execute the application. And the blockchain can also act as a database for the variables (and even files) for that application.
Does that make some sense?
My college years are now officially over!
I had my final thesis presentation and defense on Monday. I got an 8 out of 10 for my thesis, which is equivalent to an A or A+ I think? Above average at least. My thesis committee really liked the parts I cared about and had some good feedback.
It was a great day, except for the fact that my family couldn't make it. They departed well on time but got stuck at a bridge that wouldn't close properly for four hours with no way to turn back. We were supposed to have dinner together afterwards. My mom was really heartbroken that she couldn't make it. In a weird turn of events, the story of the bridge and my mom made it onto the front page of the local newspaper, and now a local restaurant has offered to give us a free dinner this Friday. So at least there's a silver lining. :)
The title of engineer is protected here - you're only allowed to use it if you've graduated with an engineering degree. So besides MSc, I now get to use the "ir." title. Gonna look super fancy on business cards.
