Letting everyone edit the information is not the best move. At least untill you get a very strong community and moderation. Better just update the website by yourself. You should also work on the design of your site, now it is too "minimalistic".
About the content. Right now your website is something between coinmarketcap and bitcoin wiki. It soesn't have anything excapt information about coins ( wiki have many information about crypto influencers and dofferent features) and at the same time it have less information about coins then CMC.
Imho both CMC and bitcoin wiki can be improved which meand that you can try to take their nieches.
The only thing that I liked and that was really usefull is a list of competitors and similar projects. It might be very helpfull, at least for newbies. You can still make something usefull of your website but you need to do pretty much work.
