This depends on your bank. It would be good if you check with your particular bank, try to get their rules and regulations on crypto currency. Contact with their customer support. As you are in country where BTC is legal, I think it should not be an issue with any bank.

Somehow that has to be true. There were experiences that I've read before that have a bias bank towards crypto and if they have found out that you did a transaction through cryptocurrency, they might actually lock your account. That was based on those experiences shared that I've read. But it can also be not particular to your bank.

sorry if I am wrong

The point that I got is, first you want to buy crypto with the balance in your account, but you are afraid that the account will be locked because the bank in your country does not allow exchange with crypto.
second, what if you create an account in ASIA, then do a crypto exchange, because banks in Asia allow exchanges with crypto.

means the solution is you have to find a bank that supports crypto exchanges. and that means you have to create a new account.
Second, if you create an account in Asia, that means you have to go to Asia first, and create an account there.

I thought it was too complicated. Aren't there currently crypto exchanges that use fiat money directly, for example, try to buy it from a closest friend, then send it through the exchange wallet you are using.
I think it is quite effective to avoid things that are not allowed in your country.

Just a few minutes ago, @womanderful started a thread on my/our local board on the matter (see Mover dinero entre bancos y exchanges). The context is currently Spain, and does not currently seem to extend to other latam countries, although anyone is welcome to chip-in in Spanish, regardless.

It’s seemingly difficult to create an updated list of people's experience that crosses the bank name on one axis, and the experience to/from a given Exchange on the other. First, there’s the issue of the sheer low volume of people on my/our local board. Then there’s the privacy concern to come forward with the experience, and then there’s the varying result for people transferring to/form a given <bank,exchange> pair, being positive is some cases and quite the opposite in others.

One should probably resort to consulting with the bank itself to make sure they won’t have any issue with to/fro TXs with a given Exchange. If there’s written proof, all the better. Nevertheless, not all bank personnel are likely to be well informed, so I’d try to contrast in addition with other people using the same <bank,exchange,[country]> touple.

Certainly this is agreeable. Before engaging or deciding to buy Bitcoin. First do a background check about the policies that is existent in your country to avoid trouble concerning legal matters because there are certain countries that already have existing legal policies concerning cryptocurrency usages to protect the welfare of their people. By doing this, you can also know what exactly your country stands about Bitcoin and other cryptocurrency as well. After knowing that, now learn from the basics before you decide on purchasing Bitcoin. You must know first basic information you must know about Bitcoin so you can effectively make use of it once you have already purchased it. Buy only on trusted exchanges and avoid strange or newly established exchanges for your own safety. Better secure yourself on engaging first on well-known exchanges that suits your preference since you are just new in the industry.

Well you can buy or invest in bitcoin of money in which you can afford to lose. There is no need to worry about bitcoin scam concept in my opinion. There are many here that can attest that investing in bitcoin might be good. However, if you wish to earn then buying later part like when market is low and then sell when market is high. Bitcoin can be one of the best form if investment but with its risks you should do your own research.

The conversion rates to USD and transfer fees is what I was thinking while reading your main post. Most banks usually charges a lot since it involves more work.

This means you already have an existing account in Citibank am I correct?
I found a survey about crypto friendly banks at Singapore and it isn't looking good https://moonbanking.com/bank?country=SG&bankKey=6ZFLlV7NpSbbov1&bankName=Citibank
It was only 3 votes and I don't know when was it taken so you can either ignore it or be warned.

There is a wallet called Abra where you can buy bitcoin directly through their app. It appears that they support direct local bank transfers such as Citibank and also accepts Singaporean Dollar so there's no need to convert to USD.

One of the most complete exchange platforms to buy Bitcoin around the world is Binance. It will be convenient for you to explore the ways to buy Bitcoin and if any are familiar to you, "case solved" because some user like you is already buying Bitcoin. The recommendations of colleagues is also ideal because you must be sure if your country does not prohibit buying Bitcoin so that you avoid any sanction in your bank account. If you make a purchase in the P2P market I doubt that the bank will relate it to Bitcoin.

You can search for local sellers on social media. I am sure you can find any local sellers, and you can check one by one of them. If necessary, you can arrange a meeting with them to buy bitcoin directly face to face, and you can send the money via ATM or your mobile phone if you can access your bank account from your mobile phone. You and local sellers can use bitcoin's current rate, and I think the fee will not be too big because you only buy bitcoin directly from them.

That can prevent you from fills KYC because you don't visit the site/exchange, and you only buy bitcoin from the local sellers. Please do not start with a huge amount of money to buy bitcoin because that can make your bank suspicious with the transaction, but you can make a small transaction. Maybe less than $100-$500 will be fine as a start.
