Is this ideal or let me use the word most suitable, I plan not to buy Ethereum until the merge is complete because

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.

2. Many exchanges already halted every Eth transactions starting from today and that's even on other chains as well, I think they knew anything could go wrong, even erc20 tokens can't be processed or sent when the merge is close am I right?

I am open to learning more about crypto, if you think there are things I don't understand please do correct me in a friendly way, God bless
