Eth is more trustable and easy to transact but still why bitcoin is on first choice
Trustable? How can you trust a coin with a centralized authority? Vitalik and his founders were made multi-millionaires with the release of Ethereum's pre-mine. Vitalik even had discussions with the Russian president, Putin and we know how corrupt he is.
I will never trust a coin with a identifiable central authority, because these people can be bribed, forced with violence to do what other people wants them to do.
