In my opinion the good altcoin currently for us to buy is Ethereum. because ETH prices will definitely rise again early next year. even I myself have bought some ETH for storage while waiting for prices to rise and market conditions to stabilize.
Yes, ETH is a strong and powerful competitor in the market continuous price fluctuation and ICO scammers has disastered the reputation of ETH and I strongly believe it will come back harder and regain its position. Yes it will take sometime to see a descent change in the market until then we need to wait patiently and watch the twist.
