My biggest concern is scalability, obviously, but there is other challenges as well. I was just wondering if anybody has been studying the subject before and can share her/his ideas with me?
Have you heard of the lightning network? My understanding is that atomic swaps would use that. So, it's highly scalable. You can buy litecoin 100 times over the span of a month using one bitcoin transaction and one litecoin transaction.
In theory, yes. But we if do not see that it is possible in practice, we have nothing. I would rather see Bitsquare developed further and used more. It is a more practical solution in the state of the technology that we have now in my opinion.
