Bitcoin's chain has limited capacity and it's being hammered by the current hype. Lower fees are possible if you control the right wallet but many services have a fixed fee that you have no control over. They'll always go for fee overkill to avoid customer complaints.
What other coins interest you and what country do you live in? That'll influence your options. Changelly is slightly last resortish.
I'm not sure which services have a fixed fee. For beginners, I know that blockchain.info is a pretty common wallet, but I know that you can adjust fee on that service. Electrum and other wallets that more experienced people use almost always have an adjustable fee amount.
Regardless of that, I think it's not worth it to put a small fee in with your transaction. Most services need at least 1 confirmation, so you want to hit that ASAP. If you don't, your transaction could be reversed. For now, try to wait it out a little. It's possible that fees go down soon, but if you really need to get a transaction through, maybe you could try to move more $ in a single transaction.
