I need urgent help. My brother just asked a question , but i failed to answer or give the best solution. My Brother just got 10 My Ether Wallets (MEW) and have some tokens and ETH in it. Now he wanted to centralize those 10 wallets into one.
The current GAS fee is currently appx $2.14 , he just got 5 different tokens or coins with some ETH. Then the total costing for centralization of one account is $5*$2.14 = $10.7 , Then to centralize 10 wallet into one will be $10.7 *10 = $107. Now i have following question --
1. Is there any other way to centralize ether and all the tokens into one wallet ?
2. Is there any way to minimize the transaction fee (GAS)
3. What is internal transaction , i saw in internal transaction the fee is low than normal. Is it possible to implement here.
Please give me a way out.
