If I may ask the Iceland you live in, is it your original home, or you just moved there with you family for some sort of reasons?

How do you cope with work living in area like that, Or you work from home ?

Now that you have gotten your self a generator which can get you a stable power supply, another challenge here will be petroleum since it took you some years to gather up funds to buy the generator how do you intend to buy petroleum on a daily basis.

If I was to be on you shoe I could have chosen a solar inverter rather than that generator, it will cost you a kind of more than that of the generator but after the installation you won't have to worry about Petroleum again, and since it's just for the purpose of  Bitcoin learning and investment, you won't need much power so it will serve you more...

You should also be aware that Bitcoin investment won't give you instant profit, Incase you have fast ROI in mind.

My advice Learn you strategy well before you start your investment so that you don't get disappointed at any point.

it must be difficult in a place that lacks facilities like that, sometimes it's difficult in a place with complete facilities.
but don't get discouraged, to invest in bitcoin you don't need to check the market every day, with that facility you can definitely invest in bitcoin.
keep spirit and don't give up.

I believe you have done pretty well considering you have been able to solve the major problem of your Bitcoin cream which is power by getting that Generator and I believe access to the internet is not an option. That said, understanding the market is a big deal so it is equally important as some have mentioned to get materials that will teach you about Bitcoin and the market sentiment.

This is probably far from ideal, but you can already generate a Bitcoin wallet without electricity, however you probably need a way of verifying it or when you do have electricity you can download a wallet, verify it, and then create a seed. Get the addresses, write them down physically, and verify they're correct. Then you can provide that address to anyone whenever you want to receive Bitcoin, completely offline. Not ideal, I know. For learning Bitcoin, you could try, and get some books first of all. Understand the fundamentals, and proceed with the above method of receiving funds. Sending funds would be more difficult, and would require internet access.

Honestly I dont understand your situation completely, since you seem to be able to chat in the forum. If you are able to do this, then you can read about bitcoin. If the internet connection or the power is only temporarily I would advise you to buy books about bitcoin or download/print stuff.
Here you can find books about bitcoin: https://www.investopedia.com/articles/personal-finance/092916/top-6-books-learn-about-bitcoin.asp
Those are specifically for beginners and can be a good option in any case.
If you have the money, buy a hardware wallet. If you dont have it, store coins on paper wallets and for daily payment use a mobile wallet on your phone.

Most important things to learn Bitcoin is a smart phone or a computer. Obviously, you need electricity to charge them. When you need to use a generator or another source of power supply, your situation gets worse. Why solar would be more expensive than a generator is beyond me. For constant power source, solar would be preferred. You can learn about cryptocurrency there, though, because you have access to the internet. Proceed to discover more. Consider purchasing a solar panel, even a small one that can power your smartphone.

Anything that's capable of running a computer for a decent amount of time is going to cost in excess of £1000. I know there's a lot of Chinese brands which have dived into the portable power storage solutions. However, can't really comment on their reliability or their safety. However, this seems a rather extreme measure just for Bitcoin. If it has a use for additional things other than Bitcoin, sure why not. Otherwise, operating offline seems to be the most cost effective solution to me, at least if you're only needing to receive, and not send often.

Most laptops can't run for longer than 12 hours so it would probably get you to 24 hours on the lowest power settings. There are laptops which can do more. There's a Panasonic toughbook which claims to reach around 40 hours, but I've personally never been able to replicate their claims. However, I do tend to run more intensive operating systems than they test on.

You can learn about Bitcoin by many resources on the Internet (websites, forums, Github, Youtube channels) or paper books or e-books. Fortunately with paper books or e-books, you can learn about Bitcoin everywhere.

Mastering Bitcoin (Github).

You can get your bitcoin wallet (Bitcoin Core, Electrum or hardware wallets) and use it to store your bitcoins, bring it around and don't need to have constant Internet connection.

It sounds great as you managed to buy an electricity generator for yourself. Have you ever thought of solar panels?

Of course, the presence of solar panels would be an ideal solution for the OP, but this requires additional funds in which, judging by his story, he is limited. But just the fact that a person striving to study bitcoin, including, has solved to some extent his problem with power outages, already inspires hope that he will persistently go further.
