Bitcoin and Ethereum in its current implementation uses Proof of Work, which is a very energy intensive process, and the energy used helps protect the network by ensuring its very costly for bad actors to attack the network.
For newer blockchains like Cosmos, which uses Proof of Stake and Solana which uses Proof of History, they have other mechanisms to protect from a 51% attack, and so does not need the validator/miners to consume energy like the Proof of Work consensus systems.
Not sure why you have to be so snarky about this. Yes, USDT has dubious backgrounds/origins... but there are lots of other reputable proejcts out there.
It's a synthetic stock which is overcollateralized by stablecoins. So for example, if $100 dollars worth of the stock is issued, someone else had to lock up $150 dollars worth of USD to issue it. And when the price rises (and hence collateralization ratio drops), the issuer has to constantly top up collateral or run the risk of them being liquidated.
How do they get price to track the real stock? By simple incentives. If the synthetic stock is trading lower than the real price, people have incentive to buy it. If it is trading above, people can easily mint new stock and sell it.
There are lots of benefits to this:
1. It allows people who typically might not have access to the US market to get price exposure to US companies
2. It allows 24/7 trading
3. US stocks are just the start, before more innovative synthetic products can be built on top.
I'm an Airbnb host who has been doing it for close to 6 months now. I'm currently renting out a studio apartment unit (around 550 sq feet) with an annualized rental yield close to 10% (one reason the yield is so high is because I bought the place 3-4 years ago while it was still under construction).
Airbnb is relatively straight forward. Check-in and check-out can be done via a key drop (typically the mailbox with a combination lock). The main thing you have to worry about is cleaning up after every guest... some guests don't know how to clean up after themselves. Get second hand furniture to save costs.
I really recommend that you try it. The business model behind Airbnb is quite brilliant.

From a research report from a local university: The institution of National Service is largely regarded as a social equaliser, which embodies fairness, equality and identity. More than 94% of respondents agree that Servicemen from different family backgrounds are treated equally during National Service, and that National Service policies are applied consistently to everyone in similar situations. [1]
In other words, it doesn't matter if you are the son of a millionaire or a janitor, in the army, they treat you the same. Beyond that it forces people to meet people from all sorts of socio-economic levels. And National Service extends until you are around 40 years old, whereby every year they may call you up to serve alongside CEOs', professionals, blue collar workers etc in the army.
Singapore is a very rich country, and it is inevitable that there are the very rich, and the less wealthy. What the government has done is made a very affordable world-class education system that allows everybody an equal chance to equip themselves to succeed in life.
When I read your reply I had to laugh and comment. I'm not sure where you got your impression of Singapore, but I think you are truly misinformed. May I ask have you ever been to Singapore or you just formed your own opinions of it online? I'm a foreigner living in Singapore for the past 7 or so years and who has gone through the education system here.
> significantly racially charged
What evidence do you have of this? In your other comment you say they come in with significantly restricted rights -> what does that even mean? First I will say that no one is forcing anybody to come into Singapore. These migrant workers come to Singapore because after weighing the odds, they feel that they can get a better life in Singapore instead of their home countries.
> class-entrenched society
In Singapore we have National Service. From the richest to the poorest Singaporeans, you serve national service together side-by-side doing the same thing. There is virtually no way of avoiding NS and there are heavy penalties if you do. Even the prime minister's children serve NS.
On top of that more than 80% of the population live in government housing flats. And these flats are not cheap, some of the bigger units have sold for more than 1 million dollars.
> rose to power on a platform of communism
This is the funniest part. The government was so against communism that communist leaders were jailed... and this harsh treatment of communist leaders is a common critic of Singapore. So for you to say they rose to power on the platform of communism just shows the depth of your misunderstanding.
Now, Singapore is not perfect. But trust me, its far better than whatever picture you are trying to paint of it.
Just a thought.. instead of building something that sends out an email... it would be much more convenient to build something that automatically adds each new book to your account.. using something like Python's Selenium library to do it.
If I were you, I would just spend some money and get a professional template like http://templatic.com/cms-themes/iphone-app which is specially for you to sell apps. (It's a wordpress theme)
This particular theme may not suite your genre of app, but I'm sure on the internet there are many. Also as for promotion, maybe you would like to contact freeappaday.com which does promotion - but you would have to offer your app free for a few days.
