Is there some way to buy Bitcoin with my “locked up” funds for my pre-paid mobile phone number?

I have a cellphone, which is disassembled > 99% of the time. Once a year, one day before it "expires", I assemble it (sticking in the SIM card and battery), power it on and pay 100 SEK (the minimal possible amount) om Comviq's website to "top it up". Not that it needs to be "topped up", but if you don't do it at least once a year, they delete your number. In other words, they force me to waste at least 100 SEK per year simply to keep the phone in working order for the possible future need to send…

What exactly is Bitcoin and how to I mine it?

I'm an amateur Python developer and I've been fascinated by the whole Bitcoin system lately.

(I hope I got that correct) I understood all that. But what I don't understand is how do you mine bitcoin and how does it give me a profit? And why do you need hi-tech like Nvidia RTX Series for mining. What are the BTC Platforms and how does programming come in handy in the world of Crypto-Currencies. How…

I sent BTC from Paxful to an exchange called LAtoken. $36 worth of BTC was sent, nothing major to anyone else but really huge to me. Cope pasted and confirmed address. NO btc arrived almost a day later. When I check on the blockchain the address says "This address has transacted 2 times on the Bitcoin blockchain.

Question about “Lost” Bitcoin

I understand bitcoin is a ledger. Everything is accounted for. If something is debited from one side, it is credited to the other, and vice versa. If a coin is sent to a wallet, with a public key, that doesn’t exist, the coins are considered “lost”. But they are still debited from the wallet that sent it and credited to the wallet that doesn’t exist. If a new wallet is created, and by mere chance, is the same address as the one the “lost” coins were sent, would those coins there when the wallet was created? Example: coins were sent…

Can i (an onlineshop) accept EU or SOFORT bank transfer but receive bitcoins (ie a “exchange-as-you-buy” via exchange-provided bank account)?

Currently i only accept Bitcoin but i want to offer customers a bank account to pay into or some kind of shop-integrated form (maybe even SOFORT/klarna) so they don't have to buy Bitcoins at an exchange before paying me. Is there any exchange or service the offers this or anything that makes the customer experience as easy as possible without them knowing anything about bitcoins and only having a bank account? I highly appreciate any suggestion, Thanks!
