Bridging is expensive and you need to bridge to both the zksync lite and zksync era networks. Also there are fees such as if you want to use Zksync Lite you need to pay to get the account activated to be able to send anything. And after a few times it adds up. The network is not cheap like Polygon.
Well, it's clear that we need a patience here. Some of us already have that anyway. It was Bitcoin who taught us before, so it's going to be easy for now to do it in other projects. The next requirement would be is the capital because you said interacting on Zsync is not cheap? But if we have other cryptos and we think they are getting weaker, maybe we can sacrifice them here for a while for a better return. We can always re-invest on them later on if we still want to.
