I lean Maxi, though I do see value in some other chains (though likely any valuable “innovation” done in the alt coin space will make its way to BTC eventually).
However two things keep resonating with me and BTC…
1). No leader/head = clean monetary policy/decentralization
2). BTC is the store of value everyone agrees on (while most alt coins are investment in the tech) and the one the world will buy into for savings/holding value/investments = scale
Therefore BTC will be the hard money or the future, which makes sense to build L2s and beyond from there without needing to deal with wrapped coins or bridges.
