So, what are your opinions... if Bitcoin gets trouble, could Ethereum become the crypto-leader?
No Way.
although you have to first define "trouble" many think confirmation time or block size is trouble or many other things that are really not an issue at all.
but eve if something happened, the next thing to come up would be Litecoin. and ethereum has been having a lot of troubles from the start that will never let it get even close to bitcoin no matter how big they make its marketcap. besides a large percentage of available ETH is in the hands of a few.
But at end of day ETH was something new to crypto while LTC is just BTC clone with better distribution but no matter what always you will find people who will complain at it.
In REAL economy something valuable is handed by few sir. Today 1% have 99% of all good on the world. So situation with BTC like in ETH is similar to that point where rich have more than poor. Yeach that difference is stunning but real this is real world in people were trying to be equal and have equal how it ends we see in North Korea where everybody have equal that mean NOTHING no goods no any freedom. People should not be mad that some whales are hoarding a lot founds if we had real life in utopia then distribution in BTC, ETH would be more fair but real life is not utopia.
