This is kind of a vague question- the blockchain cannot eradicate and erase poverty.
Blockchain changes the world and it brings more jobs to people who want to learn and find new jobs in a new industry. However, it can not give jobs or income to lazy people who call blockchain is a fraud industry and never want to begin learning about blockchain.
People can only get income, get richer if they are laborious in learning and working.
I actually do not know in what manner Bitcoin can cause chaos or problems in the world, quite a lot of world problems and chaos are caused by governments, Bitcoin is just a network that gives users freedom to use their funds how they deem fit and without the government controlling it, that can in no way cause chaos.
Bitcoin and the network give us freedom to store our asset in Bitcoin, in non custodial wallets. It gives us mean to do transactions privately, on a decentralized network that is not controlled by governments.
It does not give us income so it can not end poverty anywhere on Earth.
