If you, for example, choose the 3 day plan, the minimum amount is 0.005 BTC and 0.5 ETH for Ethereum investment. For the 10 day plan it’s 0.2 BTC and 10 ETH & for the 30 day plan it’s 1 BTC and 100 ETH. Make sure that your deposit is not less than the minimum amount required. Anything under the minimum requirements will not be processed and will get returned back to the sender’s wallet address.
