I don't know what electronicash think about altcoins. but for me not all of them are scams and useless. there are so many altcoins which are really good. they are useful as well as profitable and legit. I've been into altcoin for a long time now and I have make a lot of profit from altcoins. from some new altcoins and from some established altcoins like ethereum. Xrp and Dogecoin.
so for me all altcoins are not scam.
It is true, it cannot be underestimated that there are several altcoins that have provided huge profits for traders, both small traders and large traders who have long interacted with altcoins. Of course this is inseparable from the right altcoin. Care is needed in choosing which altcoins to invest in. I agree that I have personally benefited from alltcoin especially Ethereum and Dogecoin, which have consistently provided benefits for all of us.
