Hello, I bought about one hundred dollars worth a few months ago. I know I can buy things. Is it legal for me to sell back to coinbase. Im an American citizen. I'm not a merchant of any kind. Thanks.
If it few months ago, then you could make profit because this exchange sites are always sure to ensure the spread between buying and selling is high so one will not make profit from them easily. Like if I buy for $700 then I will be able to sell for like $650 by that I will make loss by selling back to them. So if you have confirm that, then you can go to the next phase if you are allowed to sell to them and another way around it, is to use localbitcoins.com I am sure you can make more going that route.
