BTC is already the backbone currency. Yes it has problems but those problems can be resolved. And who actually runs a full node nowadays? Most wallets are online.
I think this bubble will pop long before any other coin reaches 1000.00
That's part of the problem....how can BTC remain secure as a backbone, if the issues are not fixes, dev stalls or rather the implementation of dev reaches to many impasses, and people cannot easily run a full node nor are incentivized correctly to do each thing.
