Well well well where do i sign!?

So I stumbled across RVN last night and got interested in investing a few bucks.

i am pretty new to the crypto world so i hope my questions are not too "dumb"

​

1. Where can I buy RVN?
2. Can you buy RVN at all or do you have to mine it?
3. What wallet do you guys use?
4. Is it possible to hold RVN?
5. Is RVN even a crypto to hold? (profit wise)

​

Thanks for reading.
