It’s something to look into if you are an expat who is sending money back to your country. Many latam countries are receiving money from abroad in this manner. All in all, it should help you to save of fees, and speed up the delivery process, and probably saveguard against inflation … but it comes with a learning curve, both for the sender and the receiver.

In addition, you need to be completely sure that the recipient is going to be able to use those BTCs directly (which is more likely in Venezuela, and perhaps Argentina now than in other latam countries), or sell them off at an Exchange or p2p site without any issues.

You've made the right choice. With Bitcoin, you can do away with high fees, long transaction and clearing periods, and of course unreliable third parties such as the banks.

I'd go straight to the point. First, you need to have a Bitcoin wallet. You may choose Electrum, Bitcoin Core, or other reliable wallets. The same goes to the person you'd be doing transaction with. With the wallet comes the Bitcoin address. You're going to be needing those addresses for your transactions.

For buying Bitcoin, you can do it here in this forum or with sites such as Binance, Coinbase, BestChange, Robinhood, etc.

Please be informed that there is risk in every step of the way. Always do a careful research first. Always double check. Ask questions.

Then the recipient (or a trusted proxy) would need to sell the BTCs at an Exchange of p2p site, and transfer the fiat (Chilean pesos) over to the desired bank account.
There are things to query though on the recipient’s side, such as if the bank would have any issues receiving fiat from an Exchange (or explore the p2p route), and if the transferred funds would amount to any value that may trigger some clearance process at the bank.

I’m not familiar with what Exchanges people use in Chile, nor their current regulation status in practice, but you can get an idea from this article:

Note: there's a Spanish local board here. It's not too active, and I'm not aware of any current poster from Chile there now.

You only need a Currency to buy bitcoin and after getting bitcoin it knows no boundaries, it can be sent to any part of the world and it doesn't work base on your location or anything, you just have to tell the other party or your friend to get his or her own bitcoin wallet and ask for his or her bitcoin address to send the Bitcoin.

.
You need to considered the price of Bitcoin which is volatile , if you want to transfer money to other person then the value you send to him or sended to you will not be the same amount you want to recieve . If you can accept that then it is better alternative considered also the transaction fee you need to use when sending BTC .

Transferring money to other people is easy using crypto currency it's only up to your country if you can easily buy it there.If you can find local exchange that automatically converted your Bitcoin to your local currency you can also use that service.
