There's no a lot of new projects that interested developing the bitcoin related product through the second layer solution like RSK or lightning.
This is not a big problem for me. The question is when will the real time fast BTC bridge from RBTC to the BTC will be available? this is also making the bitcoin holders will be much more easier to bridge or unbridge their bitcoin to the RBTC to use the sovryn platform. Massive marketing totally needed
