How do you use https://mempool.space ?
I put in a random btc address that I found online (Laptop is at home) and it shows 25 of 111 transactions.

So when I go to https://bitcoindata.science/plot-your-transaction-in-mempool.html, is the 25 or the 111 the input? And if I just send to an exchange, is that considered 1 output? I like this website ... it calculates the Transaction fees for me, pending the input / output question.

Also, https://withdrawalfees.com/coins/bitcoin is missing coinbase? Isn't coinbase not one of the exchanges? Else, that is a very helpful site. I like it! Thank you so much.

Thank you all.

I'll probably get with an accountant when I sell because I don't know how it'll all work.
Spoke to my uncle over the holidays, and he said, he sold one of his very small piece of land that he bought long time ago when he first moved to Australia, to a friend's friend. Btc was part of the agreed  payment type besides some cash. His friend helped him split the btc to different wallets which he had been giving away to his kids, nieces and nephews.

How do you set password to wallet on Bitcoin Core? Laptop is on Windows 10; very old laptop that I don't use for anything else except to run Bitcoin Core.

JohnBitCo & LoyceV  :
Bitcoin Core program shows 1.00000000. Is that 1mBTC or 1BTC? From this https://www.cryps.info/en/mBTC_to_USD/1/, looks like 1mBTC = USD47.86 at this time? If that's correct, won't Bitcoin Core show 0.001?

I don't know why in wallet.dat form - I'll try to remember to ask him the next time I talk to him. He's on a very different time zone, on the opposite side of the world.
I'm not planning to get into fiat (USD); I'm planning to move to Ethereum (which at this time seems more stable). I just thought I have to 1st convert bitcoin -> USD -> Ethereum. Didn't know I can go from bitcoin to ethereum

James_R_Simth: Thank you. I'll check Binance out. I was at coinbase yesterday looking at it, but, haven't sign up. I'm in USA but my uncle is in Australia. I don't know how it'll all work in taxes. I guess I'll find out when the prices are up and I actually sells it.

Thank you for viewing and all the suggestions. I'm learning alot.

Any pointers / suggestions on securing wallet.dat is welcome.

I see a lot of mentions of "private keys / seed phrase" in this thread. How do you get that?

I'm a newbie in cryptocurrency - My uncle gave me 1.00 bitcoin as a gift and he set up a Bitcoin Core program on one of his old laptops, that he gave me as well and added a wallet.dat file.

I'm young and hopefully won't die for a long time. But, you never know these days with covid variants. Just thought I'll create the private keys / seed phrase so I can give it to my little brother or mom, for, just in case moments - and with directions to come to this forum for help. Reading threads on here on my free time has helped me so much.

Thank you.

BlackHatCoiner: Thank you.
hosseinimr93: Thank you for the explanation. As well as the url to calculate. That's very helpful.

First of, thank you for viewing and replying.

BlackHatCoiner: No, not expecting investment advice.   Just stating my thoughts just in case anyone is wondering. Thank you for the URL and explanation.

o_e_l_e_o: Thank you. I'll check out btc / eth pair exchange then.

jackg: Thanks for the duration information. That is very helpful.

COOLCRYPTOVATOR: Yes, the replies are very helpful. Thank you for the cautions. I really appreciate it.

1 satoshi is 0.00000001, correct? When you say 1 satoshi / byte, how do I know how many bytes is my transaction? How many bytes is needed to transfer 1.0 bitcoin to an exchange?

Cryptocurrency newbie here.

Received a wallet.dat from my uncle with BTC1.00 in it according to Bitcoin Core.

If I want to trade the BTC, I guess I'll have to transfer the BTC1.00 to an exchange and trade it there. How much fee do I have to put in for the transaction to get confirmation? Also, any exchange out there that will pay for the transaction fees? I saw on https://bitcointalk.org/index.php?topic=1847.0 that transaction will finally be confirm even without fees; but, any idea how long it might be? With the current prices, I'm not in the hurry to trade.
Will taxes be withheld? Or do I just file end of April?

Is it any different if I want to trade the BTC1.00 to ethereum, perhaps? Any fees? Which exchange will allow me to do that trade without first trading it for USD then buying ethereum with the USD? Any tax obligations if I do it this way?

Why trading Bitcoin for Ethereum? From the recent price crash, the prices for Ethereum, at least to me, did not drop as much. At the time of this thread, Bitcoin drops about 28% (from 68k to 49k) whereas Ethereum drops about 13% (4800 to 4200).

Thank you.
