Neteller is just an online wallet, similar to paypal.

Do you have to buy the bitcoins on the same exchange as you want to sell them? Or can you buy them on, f.e, bitpanda, and then sell them on, f.e, coinbase?

So, Neteller has an option to transfer some of your funds into crypto (I chose bitcoin (duh)). But for the life of me I can't figure out how you're supposed to sell it. Apparently I need some BTC wallet but I thought neteller functioned as that as that's the wallet that contains my BTC...

Anyways, how are you to sell these bitcoin?
