In the case of your print screen, you are selecting source "Hive mainnet" and as a target the Bitcoin network. Because Hive does not know about the Bitcoin network, the swap will need to first transfer HIVE from the mainnet into Magi, and then because Magi can swap from HIVE to BTC, it will need a BTC address in order o perform the swap.
So, in this case what the UI is asking is for the receiver which is a Bitcoin address.
If you try the HIVE to HBD its easier to understand because you can only thing "HIVE".
If you don't know how to get a Bitcoin address you can click "deposit" Bitcoin on the main interface, and it will show your associated BTC address for your Hive account on Magi.
Hope this helps. Lets keep this going.
Ajá And if I want to have BTC in Magi... Magi provides me with a wallet, and where do I send BTC from to Magi?
Correct.
BTC is just another crypto... there are multiple places/people around the world that have BTC addresses (including crypto exchanges) and you can send BTC to them via a BTC address.
Or, you can just hold BTC (I am using BTC as an example here) because you believe the price of it is going to get higher in the future (and then you can trade BTC for another crypto or fiat/Dollars/etc).
To add "liquidity" to a pool of Magi (and currently there are only 2 pools) you always need to have liquid (in Magi) of the pair. So if at pool price, 1BTC is 1Million HIVE, then that's a 1/1Million ratio. Which means if you want to add 0.0000000001 BTC, you need at least 1 HIVE to be able to add the pair BTC/HIVE to the pool (this works in general the same way with pools everywhere, not just on Magi).
You can also receive BTC on your Magi associated BTC address (that you can check on deposit button). And if for example, someone else on the BTC network sends you some BTC, you will receive it there, by providing that BTC address to the other person.
So effectively I could send you BTC from my Magi BTC address, into your Magi BTC address.
We are not going to do it, because it has fees and unless you send large amounts its not worth it. But when doing such thing, it will appear on the BTC network, and in this case because you are doing it via Magi, also on the HIVE ledger (where Magi runs on top).
I understand. If there's electricity tomorrow, I'll get to it. Thank you, thank you, thank you.
Sucks... really puts into perspective the world we live in.
Save some energy then. See you tomorrow.
