Basing on my knowledge, understanding and learnings from our website you can earn ethereum by looking for campaigns that can give you back ethereum by joining them and investing.There are Limited campaigns that pays you ethereum basing on my expectations I only found altcoins. You can go mining as well but great amount of money must get out from your hands and you can get ethereum with faucets  as well but You need to spend many time to get a large amount by doing it for more than a year so faucets for me is a last option when it comes to faucets. You can just use this if you need fees.
