Don't sympathize with my sister! I've given her family 5Btc and 500 ETH in the last year just for being my sister. She has no clue what to do with it! Kinda tacky to ask for it back😳
I think it is good if she does not know what to do with it. She can hold them and be very rich in the next few decades.
I am quite sure about the future of bitcoin. I am not so sure about the Ethereum. I hope the Ethereum will survive.
