To host website on Qortal blockchain should I be more than Lvl 0 ? Or it doesn't matter ?
Level does not matter, you'll only require some QORT to register your name and you'll be all set.
Good, thank you for an answer.
And what about buy orders on trade portal ?
People still can't place order to buy at price they want. Why ?
So many new versions of the Core and UI have been released lately, but there are no positive changes on this issue.
The Qortal UI now has 'auto buy' - this functionality essentially allows for 'buy orders' to take place on the trade portal.
You can put in an amount of QORT you wish to buy, and price you're willing to buy up to. Auto buy does the rest. Picks up every order under the price you set, starting at the lowest and working its way up, that you can afford.
The auto buy orders are not 'public' so that is essentially the only 'difference' between auto buy and a 'buy order' in the sense that most people are thinking of when they say 'buy orders'.
There are technical reasons as to why on-chain buy orders are not a thing, as the other coins involved in the trades need to be able to be 'escrowed' such as QORT is in the AT during the placement of a sell order.
We have discussed methods among the developers to make this take place with the existing AT system of Qortal, and we believe it is possible, but it is not the primary development focus right now.
The development is currently focused on Q-Apps, which will allow essentially any application to be built on top of Qortal's infrastructure. This is an extremely exciting new addition to the Qortal Data Network, and will allow essentially everything people use on 'the internet' to be rebuilt on top of Qortal easily. Opening up multiple API calls to Q-Applications hosted on the distributed decentralized QDN.
This, along with the first few Q-Apps are the focus at the moment, to get Qortal to the point of literally being able to rebuilt anything.
