Miners will destroy bitcoin because of their greed

[kvinstar]

People say that bitcoins are decentralized, in fact it is not, ordinary users of bitcoins  benefit from the introduction of Lightning Network, while cheap and fast transactions are not beneficial for miners. because small commissions on transactions will reduce their profit at times. In the end, we get that several owners of large pools decide which bitcoin should be, and our opinion is that 99.99% of the population does not care. It turns out that bitcoin is centralized. Bitcoin will cease to be the top currency due to high transactions and slow speed, but it will be too late to implement LN, already another crypto currency will take the place of bitcoin.

the thing about mining that you are ignoring is the fact that it will ALWAYS remain profitable for miners. if the profit they make goes up, more miners will join the network, difficulty will go up and the profit comes down. if the profit drops, some miners will leave and difficulty drops and it becomes same profitable as always.

also with or without lightning network and with or without any transaction on-chain miners are currently earning nearly $170,000 per block they find. and it has been more than they need to profit from mining.

regarding LN, it will not do anything to on-chain transactions. there still is going to be a lot of on-chain transactions going on and LN will even add more to it because you need to open and close channels.
