...1. Its been years that we've been waiting for this merge to happen and there have been so many delays and postponements for the past years, I doubt things will go smoothly, what if something so catastrophic happens to Ethereum when and after the merge?. .this upgrade has not been tested yet so anything could go wrong...
On September 6, a successful Bellatrix update took place and now the Ethereum network is ready for a merger, which is already expected in a week. It should be remembered that in August, a merger was already carried out in the Goerli test network, which went smoothly. So don't worry, the merger will pass without problems.
