I always write all my passwords and 2FA key into my personal notebook. And for 2FA I use another mobile device that always stays in the house. I just need a scan QR code from my device to another device, so all the codes copy into the new device. So you can use multiple devices as well. Coinbase supports mobile verification as well. You may use that, but there is a possibility to bypass code by contacting mobile operators. Usually does not happen, but there is a chance. Better to do so as I did. So you will have multiple backups.

If you are a millionaire then shouldn't keep your funds on the smartphone. You can keep just a small amount but it shouldn't be big. Its ways are preferable to use a cold or hardware wallet to store your Bitcoin and do not share it with anyone. So even you blackmailed they wouldn't know about your hardware wallet. They could take whatever on their smartphone. We can't prevent sudden incidents or accidents. But we can try to keep safe our funds. Should be more careful about our funds if it's in cryptocurrency. That's why privacy is quite important here and few people always hide their questions related to Bitcoin.

I will cry definitely Lol. Because right now I am not holding any Bitcoin. Sell it out and wait for the dip. If in case I can buy in dip and hold Bitcoin till 100K end of this year, definitely I will sell and wait for another dip. No matter if no more down after touch 100K, because I already made a handsome profit then. I think most of the holders will attempt to sell which would lead to another dip. But I am pretty sure it will not happen.

If you strongly believe you will be a blockchain engineer then yes, you can. Your target should be stronger and walk on the way. Good to see you are walking above your merits. Means your merit earning speed is more than activity. I was the same at the beginning of my journey although earning merit during that time was tougher. There wasn't much merit source as well. Now I become a merit source and spreading merits. However, newbies would take a lesson from your achievement. Everything is possible by hard-working and contribution. Just keep up your contribution to the forum. Hope once a day you will become a Legendary blockchain engineer.

Those were in Bitcoin this year, they are lucky. This year was the most Bitcoin adaption year and we can see that impact on the price. Sadly I hold some shit coins and didn't get the benefit of Bitcoin volatility. Hope next year I could do something. I am expecting more adaption by next year. I really don't care about Bitcoin heaters. We need more adaption like El Salvador, doesn't matter the price.

Let me leave my honest opinion. An escrow should have the capability to handle the situation if something went wrong like lost funds by his mistakes or whatever. On the other hand, trust is quite important as well. An escrow provider must have enough trust & enough financial solvency. But we have to think about the situation as well. Sometimes situation would be bad for an escrow provider as well though he do not intend to rush his trust. An escrow provider should be established financially that he shouldn't sell his soul eventually for money.

Merited posts aren't really merit-worthy anyway, at least not for me as a merit source. On the other hand, I will not consider merit abuse as well. It's not a big deal really. If merit sources aren't selling merit, then let them spread merits. At least merit circulation will increase. If the sent merit amount is big then it would be a different case. But here just don't be too strict since the admin isn't too strict regarding merit distribution.

This wouldn't be a solution for a centralized exchange. Users have the right to withdraw whatever they want. A minimum or maximum withdrawal is just limited by the platform. But can't force them to empty their wallet. This problem shouldn't exist anyway. As I told above, OP needs an experienced wallet developer or exchange developer who can solve it. The fund should move hot or cold wallet entirely from the user's wallet and withdrawal call should happen from the hot wallet. Otherwise, it's quite impossible to run an exchange. That's the reason actually why exchange requires high fees than actual network fees.

Bitpay wouldn't be a good choice at all and you can't host it. Your customer has to burn high fees to use Bitpay. Here is a list of payments processors where you can compare each other and choose the right one.

I think the BTCPay server would be better for you. You can host that or may use a third party as well. You can accept altcoin also through the BTCPay server. It's open-source and non-custodial where you have all the control of your funds.

What a costly lesson! Impressive. You guys aren't just teaching your students, you directly helping Bitcoin adaption. Once your students will understand fully about Bitcoin technology then they would teach more people, friends, and family. On the other hand, they will be always on the right track since they are learning from the teacher. The teacher wouldn't give the wrong lessons at all. I am pretty sure these students definitely will thank you once in a time. Please continue teaching and introduce your students to the forum. So they could learn more easily if they have intended to do so.

Bitcoin itself is an upgraded financial ecosystem, definitely, Bitcoin would help us to an upgraded financial life. It's not just about making money, it's all over about the financial system. Same as you Bitcoin helping in my lifestyle as well. From the forum, I can earn a handsome amount which is a passive income to help my overall financial capability. Bitcoin is blessed for us except for a few people those lost funds here. But I believe most of us benefited from Bitcoin somehow those we are involved with that. Don't just spend your earning, try to save a portion in Bitcoin for the future. It would change your life after a few years.

You need to study more at first how Bitcoin works. Then you would learn how Bitcoin prices work as well. Bitcoin price fully depends on the Bitcoin community in short words. Once investors enter Bitcoin means they become a part of the community as well. So investors aren't out of the community. To be more realistic, once a major part of the community thinks they should invest in Bitcoin then demand increases, as a result, Bitcoin prices go up. The same happens when a major part of the community thinks to sell then price start dump and the rest of the community become panicked. That's how Bitcoin price works. There are a few whales that could manipulate the price for a short time, not for a long time.

I'm just confused about what exactly you tried to gain. If you aren't able to read code and don't know proper use then shouldn't play with that. You are copy-pasting someone else codes and deploying contracts. This way even hackers could steal your money. I don't know if the YouTuber is a scammer or you did something wrong. I didn't understand anything from the video. Just avoid copy-pasting others' codes and sign a transaction from your wallet. It's quite dangerous for crypto users if you can't read the code.

This isn't should the exchange wallet works. When a users make a deposit the funds should move to your cold wallet. You need just use an internal algorithm for the user's exchange account to credit and debit his balance. The user's withdrawal request should go to the hot wallet from where you will process withdrawal whether automatic or manual. You should always refill the hot wallet from your cold wallet. So there will not be a leftover amount anymore. All the centralized exchange and custodial wallets work this way. Users deposit ETH it doesn't mean he will withdraw that. He might withdraw some other coin. If the user exchanges eth with another coin and withdraws that, still will the eth balance reflects in user's wallet? Definitely not. So how the mount will leftover? It shouldn't anyway. You should hire an experienced wallet developer to make it easier.

No, it wouldn't happen ever. There will fiat always either in paper money or digital cryptocurrency. Just imagine how we evaluate the Bitcoin price? It's always with fiat. So if there is no fiat how will you evaluate the value, means Bitcoin will be valueless. Then it will just like be a fiat. On the other hand, even all countries decide to ban paper money still fiat will exist through stable coins created by the government. Without centralized money, the centralized authority wouldn't exist. So the powerful centralized organization like governments would let it happen.

This is the way of filling pockets. Also, that indicates he doesn't have enough faith in Bitcoin decentralization. Rather than he believes in doge shit. However, it's an old tactic to pump a coin by Elon. He will just crap the money from the market. He is a multi-Billionaire and he needs more. But as I can see most of the time crypto community doesn't react to his comment. Because everyone already knows how he manipulates the market and fills his bag. At least I am not following nor reacting based on his tweets. Perhaps a few more whales just follow him to take a chance.

I always say, "nothing is free in the world". Even a legit site gives you free money for some task that is not free at all. You are spending time there to complete the task. The greedy behavior is responsible for most of the scams in the cryptocurrency community. We can't control ourselves once we see some greedy offers appear in front of us. We can't prevent that really because of newbies. Always many new people coming into crypto and they are unaware of the basic scam. They think earning money from the Internet is very easy, but the reality is different. We have to build our skills first before earning money. That's what we need to explain to our nearest newbies and make awareness among the crypto community.

What a fucking inspiration! You already scam 60 thousand people. You just made them fool by the plagiarised whitepaper. They really don't know you steal content from others and fill your pocket. You already insulted them and their faith. OP didn't insult them, rather than he is helping them to know the truth. This isn't a good defense at all.

Guy's current meta HYIP is quite dangerous. Many scammers will fill their pockets this way. Just be careful when you are investing in any meta projects.

To be honest, the post wouldn't be plagiarised unless you duplicate it from somewhere else. Writing your own content by yourself wouldn't math with others anyway. But if you follow some articles during writing a post then there is a chance of matching content. In that case, you may use some free tools that mention above. Usually, we use that for plagiarism checks. Try to write content from your mind, just don't steal others' content. 

Thanks for the clarification. I appreciate your thought in this case. And thanks for the refund that sent by mistake.

Electrum only allows replacing the transaction by the fee. This means you can't double spend or cancel the transaction. But for that, you should have enabled Replace-By-Fee & edit fee option before making a transaction. The increasing fee will replace the transaction with the same address. You can't change the address from Electrum anyway (I am not sure if it's possible any new version). For double-spending, you may need to input your private key in some other tool or wallet. Then you can replace the address with a new transaction with a new address if the previous transaction hasn't been confirmed.
