About receiving a credit card to sell crypto, someone in the country would be more suited to give an answer to that question, as you will need knowledge about how the banking system works.

I looked up the legality of bitcoin in Columbia and there seems to be no impediment to selling or buying bitcoin there, so your friend could use one of the popular exchanges which has added Colombian Pesos to their list of accepted currencies.
There is also the option of a P2P exchange, but for that amount, it could take a while.

Africa is not deficient in the technological scene. The continent has a fast growing internet population and a teeming amount of youths in the population who are very interested in tech.

What is your statistics on this? In Nigeria, where I am from; Internet is quite popular and has penetrated almost the entirety of the nation, same with many other African nations.

To a very large extent. The continent has a large following for cryptocurrencies and is only limited by some government policies.

Cryptocurrencies cannot support economies, neither can it help fiat currencies. It is a peer-to-peer network which bypasses the need for a third party.

The seminar was probably a scam campaign as anyone who actually understands bitcoin would not need to create an account for others to hodl, and definitely would not need an email address.
I can assume if your introduction to bitcoin was different you could have had a very different past 7 years (from 2015). But it is never too late to get into bitcoin and locating this forum is one way to do it right as there is so much information on here that is useful to bitcoin enthusiasts.

NFTs do not operate as regular cryptocurrencies, which is one out of the total supply and a sale of one coin determines the price of the whole crypto. NFTs are different and each is sold differently as such there can be no price increase without the seller fixing the price or the buyev placing a bid, a digital art cannot simply rise I'm value, except it is put in a type of auction where no price is set and the value can ride based on seller's demands.

You are right about no volume or liquidity.

I can confirm I have received the free bets.
Thank you to Sportsbet.

No, I do not believe there is anyway to check how many times you have been banned before on the forum. The knowledge that you have been banned previously before should be enough warning to avoid the practices that actually caused you the temporary ban.
 

The OP should be able to confirm who locked it by checking whether or not they can unlock it. If it was locked by a mod, then you should not be able to 'unlock' it, AFAIK.
I can see some use for other users to know who locked a thread, especially if you want to report it to be locked. Some scammers posts a scam thread, lock it so no one replies calling them out, and unlocks it when they want to bump it.

If we consider the speculative value of bitcoin, then we would never spend it, as it has the potential to increase in price from any point. But it as great utility as a currency for exchange of value and if no one spends it, then its value cannot grow.

IMO, large purchases are more likely to attract more attention than a coffee purchase, and by not reusing addresses you could avoid being tracked. Fiat seems more attractive for a regular user however.

I do not think much about the general cryptocurrency market, as it is an unpredictable space and can spring up a surprise like NFTs at anytime. If you zoom into bitcoin, then it should be more of the same, which is the exact reason it is preferred by most to other cryptocurrencies, it is reliable and the protocol does not undergo sudden changes.

Buy more bitcoin and hodl.

Large purchases occur every time in the market and does not always reflect in the price of bitcoins. Movements of bitcoin into cold storage does not affect the market much either, especially when the motive of the transaction is just speculations.

With the current state of the market, many are looking for bullish news to lift the general market sentiment, but a rumored transfer of 40kBTC would not be enough to build resistance in the market.

Whether or not you believe in bitcoin, it is obvious that bitcoin does not consume enough electricity to be actually a topic in the global energy consumption scene. The narrative that bitcoin is an energy threat is mostly spread by governments and those with a propaganda against it.

Regulations of cryptocurrency in Nigeria are not flexible, the government has banned all financial institutions from getting involved with Bitcoin or other cryptocurrencies, meaning the only way to buy or sell Bitcoin as a Nigerian is through peer to peer transactions.

How do you plan to facilitate cryptocurrency related transactions for your business?

"In a developing African country, Nigeria"

Bitcointalk does not engage in publicity at all. As far as I know, there is just one official Twitter account and besides that, the forum is not represented on other social platforms. The reason for this could be so the forum is as similar to Bitcoin as possible. Bitcoin does not engage in publicity but rather allows users find it out and do their own research.

The forum is definitely not readily reachable to a average individual and more publicity would surely be helpful to get more users on here.

Art works have generally been used for money laundering for a very long time now, but focus is usually on fields relating to blockchain and cryptocurrency and the scams are so poorly done that it becomes very obvious.

Are majority of NFTs scams? Yes. It is an easy market to exploit considering it is trending at this point in time, similar to DeFi, ICOs, etcetera.

Ideally, this should be the case, but in reality it doesn't always happen like that. Manchester United have already suspended Greenwood from the team till further notice, showing that his career is already being affected, even though he should be presumed innocent. Social media attacks would also be a factor in this case.
Everyone should ideally stay on the fence and let the authorities investigate.

This would only have been possible before the case went public, now there is the legal court which will preside over the case and the social media one. It may be possible to use money to settle out of court so charges are not pressed, but social media and the general public would not easily forget about it and finding a club that would take the risk with him would be difficult.

At this point in time, it's best to let the law take its course after carrying out sufficient investigations.

I believe the narrative that bitcoin is only used for scams is one that would only be able to go away with time. Educating the public would go a long way, but people would tend to mistrust ideas they do not fully understand such as bitcoin and the technology behind it.
Also, majority do not care about privacy, so they would hardly understand why bitcoiners value it so much, meaning many would associate it with scams.

Just learning about this now, wish you quick recovery. Bitcoiners are tough and you will pull through.

Bitcoin operates without banks or the need for a third party, but this does  not mean we can do without it or bitcoin is a perfect replacement, it just means it operates as a P2P network.

The fact that bitcoin is irreversible once confirmed is actually a positive in my opinion as no one can regulate your funds according to their terms of service, neither can funds in your wallet be retrieved by the sender. You would put in more work to learn the basics and it could take a while, but eventually you will get a hang of it.

Why would you want to switch usernames with an account you own? You already have an account with that username.
If it is not an account owned by you, then I do not think there is any condition that would warrant a switch of usernames, being inactive or not making any post is not reason enough.

Changing display names would not affect the UIDs associated with them.

This thread should be in service section as you are looking for someone with a particular skill.

Do you have knowledge about what you wish to create;
• the financial implication,
• profit margin, considering other competitive businesses,
• legal standings in your country,
• your long term expectation?
