It is hard to get anyone to accept Paypal for crypto especially when you are a Newbie with no reputation.
You are better off buying Bitcoin using one of the well-established mechanisms and exchanging it for CLAMs.
I know I'm nobody. That's why I'm asking to do business with someone reputable in a sense. Where else to go?
Go buy Bitcoins. There are a lot of ways to do that everywhere in the world starting with localbitcoins in most places, or coinbase in not quite as many but still quite a few. Or many other ways. Then trade them for CLAMs and you are good to go.
