There is no specific blockchain for Africa nor specific miners for Africa, there is only one blockchain and miners are all over the world mining and confirming transactions which is general and not specific to a particular country or continent. The mempool right now can include transactions with feerate over 200 sat/vbytes, this is unusual. This will soon be over approximately begining of next month when mining difficulty is adjusted, their would be reduction in feerate.

But, try to make use of segwit next time, you can use electrum wallet for that rather than using wallet that do not support segwit. Blockchain.com wallet supports only legacy, this will be responsible for more teasnation fee paid, if it is native segwit you want to use, 42% or more fee would be safed as segwit fee is lower by 42% or more.

Also, know that bitcoin transaction fee is not calculated using the amount you want to send, it is calculated based on weight. If you are sending $10 worth of bitcoin with 1 input and 2 outputs, and the fee is 0.00002 BTC, the same amount of fee will cost you if even sending $1000000 worth of bitcoin having 1 input and 2 outputs.
 

 Many people want to transfer their bitcoin and the miners get to pick the transactions that get through - they generally select transactions with the higher fees.
If you only want to transfer $1 worth, you'll have to wait until the mempool is nearly empty - see April 10,11,12,13
You likely wont have to wait tooooo long.  If you don't like waiting, you can use the lightning network - https://99bitcoins.com/bitcoin/lightning-network/wallets/ (caution - some wallets are custodial - not your keys = not your coins)

I haven't ever had blockchain.com, but I guess that it keeps your private keys on their database. How's that non-custodian?

That's true. Unfortunately, difficulty re-adjusted on April 15th (block 679,392) and thus, we'll have to wait 'til block 681,408. At the moment it's 1,221 blocks away...

I too have not used the wallet before, I downloaded it just to know how the wallet was at the time, and I deleted it without using it. According to the claim by the article I have found out about the wallet which I am not sure if it is true:


So, I do not think they store private key or anything related on database, that is why the seed phrase or the wallet file is important/needed during recovery.

That quote is a damn lie from blockchain.com

i have to be super honest here. i want to say a super thank you for all who replied. i so appreciate your kindness to spare some time out of your super busy work time to reply my worries with a very fair responds with better explanations that well calm my highly worried self.  thanks a billion.

The blockchain network is pretty loaded right now, which means - if you want your transactions to be processed you gotta pay a lot. Also, it's not local, the transaction fees are equal everywhere, you do realize that your transaction can be processed by some miner thousands of miles away from you, right?

Though, $40 seems extremely high, even for times like now. Something tells me that you probably loaded your crypto wallet with many small deposits in the past, thus, increasing the weight of your transaction, which resulted in a higher fee rate.

In the future, use segwit, like many advised you here, and check the mempool if you don't want your transaction hung up.

Yes, better to check the mempool first before creating every transaction, there are already a lot of sites that can check the recommended transaction fee or satoshi/byte, and also differ in transaction size.
Another alternative for bitcoinfees.earn.com is https://coinb.in/#fees, where you can see the recommended transaction fees and you can use their fee calculator for given transaction size.

They have always stored the private keys in their database but only encrypted.
Basically when you create a wallet, your keys are generated in your browser then they are encrypted in your browser then sent to their servers to be stored there. Each time you login you then fetch the encrypted keys, decrypt them in your browser and use them there.

This way they won't have access or control over your keys (hence non-custodial) but still you are storing the keys remotely in a server that could be hacked and maybe there could be some vulnerabilities in the way they encrypt the keys which could be exploited to steal your coins!

If you're using other wallets like online wallets, which most likely doesn't support segwit addresses then you'll surely be slapped by many fees.
I even recalled back in 2017 when I transferred just like $10 worth of Bitcoin then I was asked to pay $20 for the miners/network fee.
Quite insane, eh?
When I used segwit addresses, I only paid like almost cents. I am not sure how it all gets calculated, but that should be starter for ya, OP.

Lol it’s happening to everyone no matter where you are living around the world, the cost for Bitcoin transactions has been high, and it’s not only bitcoin, a lot of other cryptocurrencies have high fees for transactions too. I have friends in different countries, and when they make transaction with bitcoin they always have to pay these high fees, and most of them have started switching to other cryptocurrencies, such as Tron.

Although I think the reason why the transaction fees of bitcoin is high like this is because there isn’t enough miners and there are too much users making transaction, and other coins are cheap because they don’t have much users yet.
