Will assets on childchains of ARDR be directly tradeable against BTC (buy and sell against BTC)?
On the nxt asset exchange you have to buy nxt first to be able to buy assets. People who want to get out of assets sell against nxt and and then exchange the nxt to other currencies causing a downward price pressure on nxt.
So if this is the same in ARDR it has the same disadvantages of nxt. But i hope it is different.
Yes.
Assets on Ardor are GLOBAL, which means you can trade them across all child chains.
When properly set up (and it's easy to do so) you can use Asset tokens to represent another currency (BTC, EUR, USD, NXT, ETH, whatever) and trade them using Ardors AE.
So you could sell an asset A on child chain 1 directly to an asset B on another childchain 2. Where Asset B represents another currency.
But how does this work? Can someone explain to me how you get the real BTC if i would, for example, sell asset A for Asset B.
I have asset B and want the real BTC it represents. What do i do?
