That is exactly why people are adding new chains, to get ready for the bull period so that they could be known to have these type of things when the time comes. We know that stake has bunch of chains right now don't we? We know that roobet doesn't have that right now don't we? Which means that when the time comes and bitcoin is once again 60k or something and ethereum is 5k whatever, the prices of each transaction will be high.
We shouldn't really be expecting roobet to do it only after it goes up and hope to god that everyone would be aware of it and not go to stake. Do it now, get it heard, and when the time comes everyone will come here because of the cheap tx fee.
New chains look good in early months but when more people use their chains, capacity to handle transactions will be overloaded and sooner or later we will see their weakness.
We will experience hiccups of new chains and more bad things. New chains also mean lack of testing and fighting against hack, compromise. You don't know when hacks will happen on new chains because their security is unknown.
They start by claiming their chains are good or bad and are created to provide smooth transactions, no congestion, no high fee. We see whar happpened with Solana, Polkadot and other new chains created last 3 years. They are not good as what they wanted and shilled to investors.
Bitcoin, Ethereum and Binance Smart Chain are best ones to use.
