Not all altcoins are scams, there are alt coin projects with growth potential that will give you good returns if you invest in and others that will not last long in the market, all you have to do is do your research well and make good decisions on where to invest. but not all are scams, ETH is definitely not a scam.

agreed. If you do a good research about crypto world, not all altcoins are scams. Anything, anywhere, any industries have good and bad. the only thing we can do is being patient and smart.
