When Ethereum was priced at 500 500, I bought some Ethereum coins to the best of my ability and kept them for the future.But a few days ago, when the price of etherium was not going up at all, but it was going down, I sold my etherium coins.I never expected the price of etherium to go up so much.But if I had that amount of etherium now, maybe I could have benefited a lot.
