It is one of the best investment today.
You can earn your money faster, but there is a risk...always.
i frankly agree that etherium is a good investment but not totally the best because there's a whole lot of coin which is much better compare to etherium and you cant earn fast money on it due to etherium is less volatile compare to some coins like bitcoin and yeah ,theres always a risk but then again its lesser to none compare to some coins like bitcoin.
