I think it is not possible to give the exact value of an ETH if the price of this currency varies over time. I think to get an idea of the price of ETH in real time it is recommended to check the price tracter on eToro. I think ETH is one of the virtual currencies that trades in large quantities. I think it will be easy to sell it by going to a cryptocurrency buying site. Also, the seller can place a sell order on a platform with lots of Ether users. Ethereum can be mined on any device that can perform the calculations. I think profitable mining should be done with powerful graphics cards. I think if you can't mine yourself it is possible to resort to computing power online, I think it is a miracle to know exactly the right time to invest in Ethereum. I think it is strongly advised to follow the evolution of the financial market. I think it's up to every investor to estimate the right time to make a purchase.
