elliptic curve is a type signing algorithm (like blake2b or sha). if you dont understand what an EC is i dont think you also understand why rolling your own would be a bad idea. the wallet/account seed (your post is semantics in my opinion, whichever seed it is you can only use once, which is a flaw) is directly related again to this issue.

Its not a elliptic curve but was a type of winternitz (Curl-P) before, then blackhat came:

And then they changed it....and no you create a iota seed just like that:

cat /dev/urandom |tr -dc A-Z9|head -c${1:-81}

And talking about scam....ethereum-classic? Bitcoin-cash?

Your talking about a flaw when you just can use a receiving seed once? Please just read the DAG article, and understand what winternitz-ots means hint (one time signing)
