One of my friend had 0.10 BTC in their coinbase account from long ago, he bought it for $35 as far as I know.
Recently, they had a few transaction in April although all of those transactions were very small but from few days ago, he can't withdraw anymore.
When you use coinbase to withdraw fund, after pasting the withdrawal address and amount, the "continue" button get enabled but now, it’s not enabled.
I'm nit getting the below point yet.
It says BTC balance is 0.09***
But above, it says, you don’t have enough fund.
What can be the problem?

Just saying, scammer may impersonate of popular escrow service and trick you to send the money. Verify everything before sending money. Always contact in bitcointalk, don't trust anyone in other platform.

Earlier paypal have started to allow people to buy sell cryptocurrency (a few) but that was totally a stupid idea (not allowing users to withdraw fund). But they are going to change their decision and allow users to withdraw fund. I think this is great decision.

Wondering why are you confused about whether paper wallet is secured or not. If someone can generate paper wallet by following steps accordingly, that will be the most safe wallet. None of the other cold wallet service is such safe.

আর একটা কথা, আপনি এত বড় পোস্ট কেন কোট করেছেন?

What’s the business model of different wallet services? I have been thinking this for a while but I didn’t get a good answer for few, specially for open source wallet like Electrum.

Anyway, can you please share what do you think about the business model of the following wallet-
1. Electrum
2. Trust Wallet/ Automic Wallet
3. Blockchain.com wallet
Actually I'm talking about monetary gain of these services.

Tether (trc20) would be the best as most people out there used to use this chain and the fee is low too. Regarding BUSD, I think not many people use it or know it, only traders from Binance knows the coin. You can make it an option but allowing only BUSD wouldn’t be discouraged.

Mismanagement of funds! I had the same situation too. I was able to gain 5x within 2 months from my initial BTC sale. But after two wrong trade, I lost half of the amount almost. Sadly
I don’t think you can recover it anymore unless you are a good trader. Instead, try to stay away from trading. Otherwise, you will get panicked, have stress too.

BSC is pretty cheaper than Ethereum chain but whatever the case is, at the end of the day, we have to talk about decentralization and that's where ETH is better of course. BSC will be more centralized in the coming future for sure.
Again, if you think using a coin in daily life, can you imagine paying $10+ fee for each tx? ETH is worst in fee. ETH fee is high for a long time.
Anyway, ETH will have version 2 launched soon and things may get changed.

Damn, I missed two  Got 11 out of 13. Is it risky for me 🥴
Actually I was not attentively reading the questions and that's where I missed two and that's the actual strength of phishing method for hackers.
It was a good one, would love to share with my community.

No way I can pay with BTC either but I had visited the best pizza maker in my local town today and had the best pizza here although I had to force them to have the bitcoin logo designed in my pizza. They refused to design the logo but I had too many requests to have the design although I haven’t said what's the logo all about.
I wish I could have celebrated the bitcoin pizza day 2140.

Laszlo purchased 2 pizza for 10000 bitcoin. If I'm correct, I have read about the whole story a few days ago but I forgot the name of the seller. In an article here in bitcointalk, I have seen some details when the seller have sold most of their bitcoin etc.
Can someone give me the link of that article in bitcointalk or share details about that seller?

I would be pretty happy to get paid in bitcoin or some other cryptos from my employer, like I get paid from some of the works I do online. Without this one, if you arr thinking to accumulate fund by trading/gambling, remember you can lose it all.

They had a huge number of traffic in a matter of short time and it’s expected to have crashed. Most of the times, in such dips, they have problem. If I'm not wrong, we had seen the same issue few months back too.
And last time, a lot of people could not close their position in future trade and had to incur huge loss. Did Binance compensate that amount? No. So, you know the risk of using such exchange, you must be known about the issue before joining Binance.

I know about Ethereum and Ravencoin which can be mined with GPU. However, there are a lot of coins which can be mined with GPU but which one do you think is better to mine with GPU. I'm not a pro here. I'm analyzing possibility of mining with GPU. I have planned to have as much as GPU on the board and start my first mining project.
Note- Please report/move the thread if this isn’t the correct board to post this.

I don't think account farming is so popular nowadays, not at least the thread you shared is related to farming because it’s not anymore possible to farm account without contributing in the forum. They have some secret plan may be.
If you google bitcointalk account buy sell, you will get a lot of forums where accounts can be sold. I don't know how much an account can be worth but considering the current number of available signature campaign and the bull market, price should be higher.

You are bringing some stupid things here by relating cryptocurrency and having passive income. Till date, crypto has certainly given good amount of profit but don’t forget that unless you are using crypto as means of currency, there's no benefit. Only having trade with crypto means nothing. It can have both affect, having passive income and losing everything you have.

Charlie had once dumped all of his LTC holding in 2017, which I think is too bad. If developer of the project dump, who would believe in the project? Although Charlie Lee has bought back later.
I doubt it would reach $1000 even by 2025. There are a lot of other interesting projects out there than Litecoin.
