Kewbit, if you look at my previous response, I gave you the benefit of the doubt and encouraged you to get an emotionally intelligent friend to tell your side of the story. If this is the response, it's clear that whether or not you were sincere about completing Haveno mobile and whether or not you wished to scam, you're far too petty an immature to work on the CSS, so the CSS was correct in its decision to close the CSS. It is a pity since Haveno mobile is a much needed part of the XMR ecosystem and I hope someone completes it.
As for BasicSwapDEX, the code is finicky and is difficult to install but it does what it says it does. It needs a lot of improving for the newbie to get right but it does work and it does have liquidity. I'd say it's about six months away from being as competitive as Haveno, and its potential for automation makes it a worthy part of the XMR ecosystem. If BasicSwapDEX mobile could ever be developed, it would be even more competitive.
PoS has two main problems: (1) It makes the blockchain less resistant. (2) the Cantillion Effect. With PoS, all it takes to do a 51% attack is to have enough XMR.
If you look at the existing financial system, you can regularly see the big players openly sabotaging themselves to either kill competition or push down prices to cause a panic and then silently buy back more than they had sold while people are still panicking or just because they are subsidized to do so (e.g. DEI). With XMR's antagonism to the existing financial system, PoS would be a death sentence. PoW + PoS changes little since you can just game the algorithm so the PoW doesn't matter.
The Cantillion Effect is essentially, people with wealth get more and more power over time to game the system because they have wealth (PoS) and not because the did anything to deserve that wealth (PoW). It's the whole reason why the financial system is the way it is now and XMR should have no part of it.
