Is there any disavantages in getting something like mycompany.money or mycompany.services?

Spam filters that will block it for no reason? People who will try to access mycompany.money.com? Are they safe, like, are they all managed by the same company that deals with the .com (ICANN?)? Any TLS/SSL problems?

Another question, is namecheap any good? I found about about them on the github student pack and they offer whoisguard and a free PositiveSSL. Unfortunately it's not a wildcard and who knows when letsencrypt will be ready. I'm not affiliated just want feedback.

Thanks!
