OP is right. I just did a search and found a guide on how to buy bitcoin through Moonpay. It says If you’re coming to MoonPay through your existing wallet, we’ll pre-fill your wallet address automatically.

Where did you get this address from? Does Moonpay (or trustwallet) say they have sent your funds to this address? As I said, the transaction made to this address doesn't seem to be Moonpay (or any other service) sending…

Are you saying you purchased bitcoin, but you don't see any funds in your wallet? I can't say for sure, but since this transaction doesn't have any change output, I doubt it's related to a Bitcoin purchase.…

By default, electrum displays 30 unused addresses in "Addresses" tab. It contains 20 receiving addresses and 10 change addresses. To OP: As already stated by LoyceV, all addresses displayed there are yours. I just want…

This is a P2PK (Pay to Public Key) transaction. P2PK transactions were common in the early days of bitcoin. These days, it's not common to send bitcoin to public key and instead we send bitcoin to the address which is a…

Very interesting thread, thank you for sharing some of your experience.

Right. Your bitcoin is always on the blockchain (By blockchain, I mean a ledger that include all bitcoin transactions, not blockchain.com website). Non-custodial wallets like electrum are tools that give you access to…

Right. If you have imported your wallet into electrum successfully, you should see your balance at the bottom left corner of the window. No. By importing your seed phrase into electrum, you don't move your fund and you…

Your seed phrase (the series of 12 words) can generate all your private keys and is all you need to recover your wallet. As already said above, just import your seed phrase into electrum and provided that it's the…

Blockchain.com has been always a buggy wallet. Since you have your seed phrase, there's nothing to worry about. You can simply import your wallet into other softwares like electrum and get access to your fund. I also…

If you have your private keys on an online device, you have a hot wallet. Any online device is always to prone to hacking and that's why it's recommended to have your private keys on an offline (preferably to be…

There is no IOS version of electrum, but that's available for macOS and you can use it on your Mac. You can see the list of operating systems supported by electrum on its official website.

With importing your private key into multiple softwares, you are risking the security of your fund. Stop it. As suggested above by OmegaStarScream, you can use electrum to get access to your fund and I just want to add…

I just edited my previous post, as I noticed I made a mistake. There are nearly 2256 valid private keys and 2160 addresses. (There are more addresses, if we consider different types of addresses). Therefore, any address…

Any public key and Any address can be generated by 2^96 private keys on average. To receive fund, you need to have a bitcoin address and give it to anyone who wants to send you bitcoin. You need the private key…

OP calculated the sum of series 210,000*50/(2^x) from x=2 to x=32 and got 5249999.998 for that. That's correct with three decimal places precision. I just calculated that with python and got 5249999.997555278. First I…

I was referring to your paper where x=2 and I thought you meant the second period by x=2. I don't understand what's the use of calculating the sum from x=2 to x=32. Yes, 21,000,000 doesn't have any decimal point and I…

You did the calculations wrongly. For example, 5,250,000 BTC were generated in the second period. I don't know how you got the 5249999.998 BTC. The total number of bitcoins will be finally 20999999.9769 With doing do,…

So, you have no idea about possible passphrases. Unless the passphrase is short and it contains only a few characters, there is no way to brute-force that. Since you say the password was set by someone else, I doubt…

Take note that a random number generator uses known mathematical formulas for generating the random number, but the output is unpredictable. Therefore, it's not that we don't know how electrum generates an entropy. We…
