they will not allow users to utilize LN channel for large payments, >XBTC TX will go through the blockchain.
No, what I'm saying is the utility of that channel is going to be next to nil, because BTC typically flows in one direction, not back-and-forth, due to the nature of arbitrage. So it will be 25 BTC from Rock to BFX, another 25 BTC from Rock to BFX, and another, and another. All small, all going in one direction, because BTC costs less on TheRock. Until things change and it starts going in a different direction, to OKCoin, which is another open channel with 50BTC stuck in it that's only good for 2 tx.
