Her birthday was just a few days ago, and I was thinking in doing something different. She already knows that I am into cryptocurrency for a long while, and she was also exploring it recently. I was asking her if she would like some Ethereum as a gift for her birthday, and she never hesitated to say yes! However, she didn't expect the amount that I've sent her.
She was expecting way less, but I sent her $100 worth of Ethereum (+$6 in gas fees) and she was all smiles thanking me for it. For me, it's such a great feeling to give her something like that, as I love her very much.
This is a very commendable act from you to your sister; and believe me she is going to remember this for a very long time to come; not only was that a gift, you have also showed her the truth that the blockchain, crypto currency and decentralized finance are the future; and she would also tell her friends; one way or the other, you have been a good ambassador to crypto currency adoption lol.
Did she later asked to find out about etherum and its likes? Also, can you make a card about the happy moment and draft out an art to be an NFT ? it would be so natural.
