I am impressed with the concept of etherium, however I can't figure out why I should buy it. I am not a programmer, If I buy 2000 ethers I can't resell it because the next buyer won't know if I held onto the wallet and used it. If I can't sell it and the value is going from 1 BTC for 2000 ethers to 1 BTC for 1300 ethers then what have I gained. I guess I don't know why I should spend 10000 dollars for some ethers. How would I get my money back?
