Sorry that is not what bitcointalk is about, it is not like a college where you can learn how to write and speak English, it is a discussion forum, and truly the language used for communicating in bitcointalk is English (except the local boards), and there are many native speakers of the language here, you can learn a little from how they write.

Needless to say that it isn't enough, and the better thing to do is to improve your English writing and speaking off the forum, there are websites you can take English courses for some months, you can also install Grammarly to assist you too, as well as many other tools out there to learn English properly. Bitcointalk is a bitcoin discussion forum, take it to be that.

Bitcointalk is honestly overrated in terms of learning in general. It's great for having questions and discuss/debate certain news and topics, but if you're a beginner you're better off reading articles off the web.

Unless you can walk into a shop make a selection of goods, go to the counter scan their QR code and pay via Bitcoin (and the transaction is confirmed near instantly as is the case with the Lightning Network), then bitcoin's only real continued attraction will be with the speculative investors with a few thousand/million cash to spare that they don't mind parking for three to six months, then the novelty wears off and dump on the next unsuspecting investor.

People have been resilient throughout history, some viruses heavily effect the young who might have a bit more strength to fight it off. Covid happens to heavily affect those over 60 years old. We're into the second year now of living with Covid and some say it may even have been circulating around October 2019. The speed with which multiple vaccines has been produced is a great thing and will really help the world get back to normal - it's just the gearing up needed to protect 7+ billion people is huge. Bill Gates has been talking about viruses for many years and clearly stated they were the biggest impending threat to humanity, shame he didn't take a bit more action to prepare for them with the huge funds his charity sits on. Give it a couple years and everything should be back to normal, hopefully the injuries it causes can be cured through time.

The pandemic totally changes everything and makes us see the world as a different thing but one thing I understand about complying with the total lockdown and dealing with the financial and the mental repercussions caused by the pandemic/lockdown is that it better to stay alive than get kill by the virus.
The only way I depressed about the financial and mental repercussions is by taking an online class and looking for an online job that will bring something good for me. In the meantime, the Greece government ought to make a huge step in getting the virus vaccine.
